Question
Light waves are _____ but not _____ in nature.
- Mechanical, transverse
- Transverse, mechanical
- Longitudinal, mechanical
- Mechanical, longitudinal
Hint:
Longitudinal waves are waves in which the vibration of the medium particles is parallel to the direction of the wave propagation.
The correct answer is: Transverse, mechanical
- When the movement of the particles is at right angles or perpendicular to the motion of the wave propagation then this type of wave is known as a transverse wave.
- Light is an example of a transverse wave.
- Light waves don't require a medium for their propagation.
- Therefore, they are non-mechanical in nature.
