Formula for wave frequency: f = s/w

f = frequency

s = speed

w = wavelength

Solve for the frequency using the given values.

f = 4/2

f = 2 Hz

Therefore, the wave frequency is 2 Hz.

Best of Luck!

Frequency of any wave = (wave speed) / (wave length)

Frequency = (4 m/s) / (2 m)

Frequency = 2/s

Frequency = 2 Hz
