Question

How does the speed of a wave relate to its wavelength and frequency?*

Answer 1

Answer: Wavespeed (V) = Frequency F x wavelength λ (V = F λ)

Explanation:

The wavespeed is the distance covered by a wave in one second. It is measured in metre per second, and represented by the symbol V. It is directly proportional to the wavelength and frequency

i.e Velocity (V) = Frequency F x wavelength λ

V = F λ

For instance:

Assume wavelength (λ)= 20 m

Frequency = 10 Hz.

To get the wavespeed, use the formula

V = F λ

V = 20 metres x 10 hertz

V = 200 metres per second

Thus, the wave travels at a speed of 200 metres per second
