Question

Which of the following statements is true about the relationship between frequency and wavelength in a wave?


As frequency increases, wavelength increases


As frequency increases, wavelength decreases


Frequency and wavelength are unrelated


Wavelength remains constant regardless of frequency changes

Answer 1

As frequency increases, wavelength decreases.

Explanation: wave speed v = frequency f × wavelength λ, so for a fixed wave speed (same medium) λ = v / f — higher f means smaller λ.
