Question

Match the following List I with List II

List-I		List-II
(A)	Transverse wave	(i)	Vibrations parallel to the direction of propagation
(B)	Longitudinal wave	(ii)	Vibrations perpendicular to the direction of propagation
(C)	Beats	(iii)	Superposition of waves travelling in the opposite directions
(D)	Stationary waves	(iv)	Superposition of waves travellina in same direction

The correct answer is

• A. (A)-(ii), (B)-(i), (C)-(iii), (D)-(iv)
• B. (A)-(ii), (B)-(i), (C)-(iv), (D)-(iii)
• C. (A)-(iii), (B)-(iv), (C)-(i), (D)-(ii)
• D. (A)-(iv), (B)-(i), (C)-(ii), (D)-(iii)

Answer 1

Answer: (B)

(b) $A \rightarrow$ In transverse wave, vibrations are perpendicular to the direction of propagation.
$B \rightarrow$ In longitudinal wave, the vibrations are parallel to the direction of propagation. $C \rightarrow$ Beats are produced due to superposition of the waves travelling in same direction.
$D \rightarrow$ Stationary waves are produced due to the superposition of waves, travelling in opposite direction.
