Solution
Correct Answer:
v = f λ
This is the fundamental relationship for all types of waves (periodic disturbances): v=fλ
- 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.
