In CBSE Class 11 Physics Paper, There will be a few questions based on case studies and passage-based as well. In that, a paragraph will be given, and then the MCQ questions based on it will be asked.

Units and Measurements Case Study Questions With Answers

Here, we have provided case-based/passage-based questions for Class 11 Physics Chapter 2 Units and Measurements

Case Study/Passage-Based Questions

Case Study 1: The rules for determining the uncertainty or error in the measured quantity in arithmetic operations can be understood from the following examples.

a.) If the length and breadth of a thin rectangular sheet are measured, using a meter scale as 16.2 cm and, 10.1 cm respectively, there are three significant figures in each measurement. It means that the length L may be written as L = 16.2 ± 0.1 cm = 16.2 cm ± 0.6 %.

Similarly, the breadth b may be written as b = 10.1 ± 0.1 cm = 10.1 cm ± 1 %

Then, the error of the product of two (or more) experimental values, using the combination of errors rule, will be L*b = 163.62 cm2 + 1.6% = 163.62 + 2.6 cm2

This leads us to quote the final result as L*b = 164 + 3 cm 2 . Here 3 cm 2 is the uncertainty or error in the estimation of the area of the rectangular sheet.

b.) If a set of experimental data is specified to n significant figures a result obtained by combining the data will also be valid to n significant figures. However, if data are subtracted, the number of significant figures can be reduced. For example, 12.9 g – 7.06 g, both specified to three significant figures, cannot properly be evaluated as 5.84 g but only as 5.8 g, as uncertainties in subtraction or addition combine in a different fashion (smallest number of decimal places rather than the number of significant figures in any of the number added or subtracted).

c.) The relative error of a value of a number specified to significant figures depends not only on n but also on the number itself. For example, the accuracy in the measurement of mass 1.02 g is ± 0.01 g whereas another measurement of 9.89 g is also accurate to ± 0.01 g. The relative error in 1.02 g is

= (± 0.01/1.02) × 100 % = ± 1%

Similarly, the relative error in 9.89 g is = (± 0.01/9.89) × 100 % = ± 0.1 %

Finally, remember that intermediate results in a multi-step computation should be calculated to one more significant figure in every measurement than the number of digits in the least precise measurement.

d.) The nature of a physical quantity is described by its dimensions. All the physical quantities represented by derived units can be expressed in terms of some combination of seven fundamental or base quantities. We shall call these base quantities the seven dimensions of the physical world, which are denoted with square brackets [ ]. Thus, length has the dimension [L], mass [M], time [T], electric current [A], thermodynamic temperature [K], luminous intensity [cd], and amount of substance [mol]. The dimensions of a physical quantity are the powers (or exponents) to which the base quantities are raised to represent that quantity. Note that using the square brackets [ ] around a quantity means that we are dealing with ‘the dimensions of’ the quantity. In mechanics, all the physical quantities can be written in terms of the dimensions [L], [M], and [T]. For example, the volume occupied by an object is expressed as the product of length, breadth, and height, or three lengths. Hence the dimensions of volume are [L] × [L] × [L] = [L 3 ].

Case Study 2: Measurement of Physical Quantity : All engineering phenomena deal with definite and measured quantities and so depend on the making of the measurement. We must be clear and precise in making these measurements. To make a measurement, the magnitude of the physical quantity (unknown) is compared. The record of a measurement consists of three parts, i.e. the dimension of the quantity, the unit which represents a standard quantity, and a number which is the ratio of the measured quantity to the standard quantity.

(i) A device which is used for measurement of length to an accuracy of about 10 -5 m, is (a) screw gauge (b) spherometer (c) vernier calipers (d) Either (a) or (b)

Answer: (d) Either (a) or (b)

(ii) Which of the technique is not used for measuring time intervals? (a) Electrical oscillator (b) Atomic clock (c) Spring oscillator (d) Decay of elementary particles

Answer: (c) Spring oscillator

Answer: (a) 4.9 cm

(iv) If the length of rectangle l = 10.5 cm, breadth b = 2.1 cm and minimum possible measurement by scale = 0.1 cm, then the area is (a) 22.0 cm 2 (b) 21.0 cm 2 (c) 22.5 cm 2 (d) 21.5 cm 2

Answer: (a) 22.0 cm2

(v) Age of the universe is about 10 10 yr, whereas the mankind has existed for 10 6 yr. For how many seconds would the man have existed, if age of universe were 1 day? (a) 9.2 s (b) 10.2 s (c) 8.6 s (d) 10.5 s

Answer: (c) 8.6 s

CBSE Case Study Questions Class 11 Physics Waves

Case study – 1.

When we speak, the sound moves outward from us, without any flow of air from one part of the medium to another. The disturbances produced in air are much less obvious and only our ears or a microphone can detect them. These patterns, which move without the actual physical transfer or flow of matter as a whole, are called waves. The most familiar type of waves such as waves on a string, water waves, sound waves, seismic waves, etc. is the so-called mechanical waves. These waves require a medium for propagation, they cannot propagate through vacuum. They involve oscillations of constituent particles and depend on the elastic properties of the medium. The electromagnetic waves that you will learn in Class XII are a different type of wave. Electromagnetic waves do not necessarily require a medium – they can travel through vacuum. Light, radio waves, X-rays, are all electromagnetic waves. We have seen that motion of mechanical waves involves oscillations of constituents of the medium. If the constituents of the medium oscillate perpendicular to the direction of wave propagation, we call the wave a transverse wave. If they oscillate along the direction of wave propagation, we call the wave a longitudinal wave. In transverse waves, the particle motion is normal to the direction of propagation of the wave. Therefore, as the wave propagates, each element of the medium undergoes a shearing strain. Transverse waves can, therefore, be propagated only in those media, which can sustain shearing stress, such as solids and not in fluids. Fluids, as well as, solids can sustain compressive strain; therefore, longitudinal waves can be propagated in all elastic media.

1) Air can sustain

d) none of these

3) Define Transverse waves

Answer key-1

4) If oscillations of constituents of the medium are along the direction of wave propagation that is parallel to direction of propagation we call the wave a longitudinal wave.

5) Following are differentiation points


1	If the constituents of the medium oscillate perpendicular to the direction of wave propagation, wave is called as transverse wave	If oscillations of constituents of the medium are along the direction of wave propagation that is parallel to direction of propagation we call the wave a longitudinal wave.
2	Can passs trough solids only	Can pass through both solids and fluids
3	Example electromagnetic waves	Example sound wave

Case Study – 2

a) a rigid boundary

Answer key – 2

3) A wave travelling in one direction will get reflected at one end, which in turn will travel and get reflected from the other end. This will go on until there is a steady wave pattern set up on the string. This wave remains steady in medium and does not travel further such wave patterns are called standing waves or stationary waves.

4) If the boundary is rigid, a pulse travelling along a stretched string and being reflected by the boundary. The reflected wave has the same shape as the incident pulse i.e. crest is reflected as crest and trough as trough but it suffers a phase change of π or 180 0 on reflection. This is because the boundary is rigid and the disturbance must have zero displacement at all times at the boundary. By the principle of superposition, this is possible only if the reflected and incident waves differ by a phase of π, so that the resultant displacement is zero. This reasoning is based on boundary condition on a rigid wall.

c) υ = (υ 1- υ 2)/2

b) decrease

Answer key – 3

d) Astrophysicists use it to measure the velocities of stars. Doctors use it to study heart beats and blood flow in different parts of the body.

e) Doctors use it to study heart beats and blood flow in different parts of the body. Here they use ultrasonic waves, and in common practice, it is called sonography. Ultrasonic waves enter the body of the person, some of them are reflected back, and give information about motion of blood and pulsation of heart valves, as well as pulsation of the heart of the foetus. In the case of heart, the picture generated is called echocardiogram.
