Wave length 3m and frequency 300 what is the speed of the wave

900 m/s

Explanation:

The wave speed can be found using the formula:

v = fa where

v is the wave speed in m/s

f is the frequency in Hz

a is the wavelength in m

Hence by applying the formula, we get:

v = (300) (3)

= 900 m/s

Hence the speed of wave is 900 m/s.
