Question

What is the wavelength of this wave if the frequency of a wave is 40 Hertz and the speed of the wave is 100 meters per second?

Answer 1

The wavelength is 2.5 m.

See a similar Socratic question.

In your problem, `v` = 100 m/s and `f` = 40 Hz, so

`λ = v/f` = `(100"m·s⁻¹")/(40"s⁻¹")` = 2.5 m
