Embibe Experts Solutions for Chapter: Wave Motion on a String, Exercise 8: Exercise (Assertion & Reason)

Assertion :In standing wave pattern particle of medium between two consecutive nodes vibrates in same phase but with different amplitude.

Reason : In stationary wave the amplitude of vibration does not depend on the position of the particle.

Assertion : The wave function of a pulse is given by $y=\frac{3}{(2x+3t+4)}$ is propagates in ($-\text{ve} x-$ direction)

Reason : The given wave function is of the form $y=f(kx+\omega t)$ which represent a wave travelling in negative $x$- direction.

Assertion : Standing waves do not transfered energy in the medium.

Reason : Every particle vibrates with its own energy and it does not share its energy with any other particle
