Question

How are wavelength and frequency related?

A.
If the speed between the crests of the waves increases, the frequency increases.

B.
If the distance between the crests of the waves decrease, the frequency decreases.

C.
If the distance between the crests of the waves increase, the frequency decreases.

D.
If the speed between the crests of the waves decreases, the frequency increases.

Answer 1

C

They are related by v = λ·f. For a given wave speed v, frequency f = v/λ, so increasing wavelength λ gives a lower frequency.
