Question

Match the following List I with List II. $\begin{array}{|c|c|c|} \hline & \text { List I } & \text { List II } \ \hline \text { (A) } & \text { Transverse wave (i) } & \begin{array}{l} \text {Vibrations parallel to the } \ \text {direction of propagation } \end{array} \ \hline \text { (B) } & \begin{array}{l} \text {Longitudinal wave } \end{array} & \begin{array}{l} \text {Vibrations perpendicular to } \ \text {the direction of propagation } \end{array} \ \hline \text { (C) } & \text { Beats } & \begin{array}{l} \text {Superposition of waves } \ \text {travelling in the opposite directions } \end{array} \ \hline \text { (D) } & \text { Stationary waves (iv) } & \begin{array}{l} \text {Superposition of waves } \ \text {travelling in same direction } \end{array} \ \hline \end{array}$ The correct answer is, $\begin{array}{cc} A & B & C & D \ (ii) & (i) & (iii) & (iv) \end{array}$, $\begin{array}{cc} A & B & C & D \ (ii) & (i) & (iv) & (iii) \end{array}$, $\begin{array}{cc} A & B & C & D \ (iii) & (iv) & (i) & (ii) \end{array}$, $\begin{array}{cc} A & B & C & D \ (iv) & (i) & (ii) & (iii) \end{array}$

MARKS App · Accepted Answer

$\mathbf{A} \rightarrow$ In transverse wave, vibrations are perpendicular to the direction of propagation. $\mathbf{B} \rightarrow$ In longitudinal wave, the vibrations are parallel to the direction of propagation. $\mathbf{C} \rightarrow$ 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. Hence, the correct code is given by option (b).
