Question

Match the statements of column A and column B:

Column A	Column B
A) Velocity of sound is constant	p) Phase change of $\mathrm{\pi }$ radian
B) Reverberation	q) Wave motion
C) Reflection of sound wave in an open tube	r) Homogeneous medium
D) Transverse wave cause	s) Change in shape of medium
E) Transfer of energy	t) Sound- absorbing materials

• A. A→ q; B→ r; C→ t; D→ p; E→ s
• B. A→ s; B→ p; C→ s; D→ r; E→ s
• C. A→ r; B→ t; C→ p; D→ s; E→ q
• D. A→ r; B→ t; C→ s; D→ p; E→ q

Answer 1

The correct option is C

A→ r; B→ t; C→ p; D→ s; E→ q

1. In a homogeneous medium, the velocity of the sound remains constant.
2. Reverberation is the phenomenon of persistence of the sound after it has been stopped due to multiple reflections. Hence, Reverberation is related to sound-absorbing materials.
3. Reflection of the sound wave in an open tube made phase change of $\mathrm{\pi }.$
4. Transverse waves cause the medium to move perpendicular to the direction of the wave.
5. Wave motion is the transfer of energy and momentum from one point of the medium to another point of the medium.

Hence, option C is correct.
