Question

Explain or don't answer :3

If the medium a wave is traveling through is constant, what about the wave can change?

A: only its speed or frequency

B: both its frequency and wavelength

C: both its amplitude and speed

D: both its speed and wavelength

Answer 1

B: both its frequency and wavelength

Step-by-step explanation:

If the medium the wave is traveling through remains the same, the speed would stay the same.

Answer 2

Because by definition a wave travels at the same speed through any given medium, A, C, and D, are all out. B is true, though. Frequency and wavelength can change within a medium itself. Therefore, B, both its frequency and wavelength, is the answer you desire.
