Solution

Correct Answer:

v = f λ

This is the fundamental relationship for all types of waves (periodic disturbances): $v = f λ$

Intuition: $f$ is the number of waves passing a point per second, and $λ$ is the length of one wave. Their product must be the total distance traveled by the wave per second (speed).
Also, since $f = 1/ T$ , $v = λ / T$ .

This easy difficulty physics question is from the chapter oscillations and waves, covering the topic of wave equation. It appeared in the 2025 exam.
