Which of the following is not true for the progressive wave

y=4 \sin 2 \pi\left(\frac{t}{0.02}-\frac{x}{100}\right)

where

x

and

y

are in

\mathrm{cm}

and

t

in second?

View answer and explanation

Correct option: D

The velocity of wave propagation is

2 \mathrm{~cm} / \mathrm{s}

Option D (Wave 2 has greatest wave speed and wave 3 has maximum transverse string speed) is correct because wave speed is

\omega/k

and transverse speed is

A\omega

.
