Question

If the velocity of a wave is 400 m/s and frequency is 100 hz, then the wavelength of the wave is :

Answer 1

Wavelength=speed/frequency
But speed = velocity
.: 400/100=4.

Answer 2

Answer:

Given

Velocity of a wave = 400 m/s

Frequency of a wave = 100 Hz

Wavelength of the wave = ?

By formula

Velocity = frequency × wavelength

400 = 100 × wavelength

400 / 100 = wavelength

wavelength = 4 m

The wavelength of the wave is 4 m .
