Question 6 • Physics

Which describes the relationship between the frequency, wavelength, and speed of a wave as the wave travels through different media?

Answer
A
As speed changes, wavelength changes and frequency remains constant.
B
As speed changes, wavelength and frequency remain constant.
C
As speed changes, wavelength and frequency change.
D
As speed changes, frequency changes and wavelength remains constant.

Explanation

Wave speed, frequency, and wavelength are related by the equation v = fλ. When a wave enters a different medium, its speed changes, while its frequency stays the same because it is set by the source. Therefore, its wavelength must change to match the new speed. This is described by “As speed changes, wavelength changes and frequency remains constant.”
