Match the following List I with List II. ( array |c|c|c| & List I & List II (A) & Transverse wave (i) & array l Vibrations parallel to the direction of propagation array (B) & array l Longitudinal wave array & array l Vibrations perpendicular to the direction of propagation array (C) & Beats & array l Superposition of waves travelling in the opposite directions array (D) & Stationary waves (iv) & array l Superpositio

Options

  1. A( array cc A & B & C & D (ii) & (i) & (iii) & (iv) array )
  2. B( array cc A & B & C & D (ii) & (i) & (iv) & (iii) array )
  3. C( array cc A & B & C & D (iii) & (iv) & (i) & (ii) array )
  4. D( array cc A & B & C & D (iv) & (i) & (ii) & (iii) array )

Correct answer

B. ( array cc A & B & C & D (ii) & (i) & (iv) & (iii) array )

Step-by-step solution

( A ) In transverse wave, vibrations are perpendicular to the direction of propagation. ( B ) In longitudinal wave, the vibrations are parallel to the direction of propagation. ( C ) Beats are produced due to superposition of the waves travelling in same direction. D ( ) Stationary waves are produced due to the superposition of waves, travelling in opposite direction. Hence, the correct code is given by option (b).
