Concepts Of Physics MCQ Edition [Volume 1]PhysicsSound Waves
The phenomenon of beats can be observed
Options
- Ain both longitudinal and transverse waves
- Bin transverse waves only
- Cin longitudinal waves only
- Din sound waves only
Correct answer
A. in both longitudinal and transverse waves
Step-by-step solution
The phenomenon of beats is based on the principle of superposition of waves. When two waves of slightly different frequencies travel in the same medium along the same direction, they superimpose to produce variations in amplitude, which are known as beats. Since the principle of superposition is applicable to all types of waves, the phenomenon of beats can be observed in both longitudinal and transverse waves.
