Question

y-x graph of a transverse wave at a given instant is shown in figure. Match the following two columns.

Answer 1

Particle velocity is related to wave velocity as

$V_P=-V_W\frac{dy}{dx}{V}_P=-V_W\times slope$

A-For particle A slope is positive so particle velocity will be negative,acceleration will be positive because it must attain its maximum velocity at mean position.

C-At B, slope is negative so particle velocity will be positive.

D-Since particle is at maximum velocity so acceleration must be zero.
