Calculate the speed for wavelenghth = 0.2 m, frequency = 5 wavelength/s

1 ms⁻¹ .

Explanation:

Speed is defined as the product of the wavelength times the frequency.

If v is the speed , λ is the given wavelength 0.2 m and frequency f is equal to 5 Hertz or wavelengths per second ,

v = λ f = 0.2 x 5 = 1 m/s
