Question

A wave has a wavelength of 2.30 m and a frequency of 370.0 Hz. What is the speed of the wave?

Answer 1

Answer is 851 on edge :)

Answer 2

Answer : The speed of the wave is 851 m/s

Explanation :

It is given that,

Wavelength of a wave is, λ = 2.3 m

The frequency of the wave is, υ = 370 Hz

The speed of the wave is given as :

$speed=\dfrac{distance}{time}$

In case of wave, the distance is equal to the wavelength of the wave and the time taken is equal to the inverse of frequency i.e. $T=\dfrac{1}{\nu}$.

So, $v=\dfrac{\lambda}{T}$

or $v=\nu \times \lambda$

$v=370\ Hz\times 2.3\ m$

v = 851 m/s

So, the speed of the wave is 851 m/s
