What is the velocity of a wave with a frequency of 10 Hz and a wavelength of 2 m?
A. 0.2 m/s
B. 20 m/s
C. 5 m/s
D. 8 m/s
SUBMIT

B. 20m/s

Explanation:

The wavelength of a wave can be calculated using the formula;

λ = v/f

Where;

λ = wavelength (m)

v = velocity (m/s)

f = frequency (Hz)

According to the information provided in this question; the wave has a wavelength (λ) of 2m and a frequency (f) of 10Hz.

Using λ = v/f

v = λ × f

v = 2 × 10

v = 20m/s.
