Question
What are the two types of mechanical waves?
- Transverse and longitudinal
- Transverse and electromagnetic
- Electromagnetic and longitudinal
- None of the above
Hint:
One wave consists of periodic disturbances or oscillations occurring in the same direction as the wave propagation and the other wave the vibration is perpendicular to the direction of wave propagation.
The correct answer is: Transverse and longitudinal
- Mechanical waves are of two types-
- Longitudinal waves and transverse waves.
- A transverse wave is a wave whose vibration is perpendicular to the direction of wave propagation.
- This is in contrast to longitudinal waves, which propagate in the direction of oscillation. Water waves are an example of transverse waves.
- So, the correct option is a.
