Question

What is the velocity of a wave of frequency 200 Hz and wavelength 2 m?.

Answer 1

`\huge{\boxed{400 m/s}}`

Step-by-step explanation:

The velocity of the wave given it's wavelength and frequency can be found by using the formula

`\large{v = f * \lambda}`

where

f is the frequency in Hz

`\lambda` is the wavelength in m

From the question

f = 200 Hz

`\lambda` = 2 m

We have

`\large{v = 200 * 2 = 400}`

We have the final answer as

400 m/s
