What is the wavelength of a 20 Hz periodic wave moving at 40 m/s?

Use the equation below!

a
80 m
b
0.5 m
c
800 m
d
2 m

1 answer

The equation needed to solve this problem is:

wavelength = speed of wave / frequency

Plugging in the given values:

wavelength = 40 m/s / 20 Hz
wavelength = 2 meters

Therefore, the wavelength of a 20 Hz periodic wave moving at 40 m/s is 2 meters. The answer is option d.
