Question

Which wave would have the greatest wave speed , a wave from a vibrating piano string in an auditorium or a sound wave created by a boat anchor striking an underwater rock

Answer 1

the one in the water would have a much greater speed than the one in the air since energy is transmitted better and faster in liquid than gas.

Answer 2

Answer:

a wave from a vibrating piano string in an auditorium

Explanation:

As we know that the speed of wave depends on two factors

1) Elasticity of medium

2) density of the medium

So here we know that

greatest speed out of the two given medium is for vibrating string of piano

as we know that

$v = \sqrt{\frac{T}{\mu}}$

so we have

more speed in stretched string
