Detailed Solution
Download Solution PDFThe correct answer is the Transverse wave.
- Light is a Transverse wave.
Key Points
- Light is a form of energy that is propagated as electromagnetic waves.
- Electromagnetic waves are transverse, hence light is a transverse wave.
- The wave nature of light explains rectilinear propagation, reflection, refraction, interference, diffraction, and polarization of light.
- In quantum theory, light is regarded as a packet or bundle of energy called the photon.
- Light behaves as wave and particle both. Thus light has dual nature.
- Speed of light is maximum in vacuum and air (3 × 108 m/s).
- Longitudinal Wave:
- If the particles of the medium vibrate in the direction of propagation of the wave, the wave is called a longitudinal wave.
- Waves on springs or sound waves in the air are examples of longitudinal waves.
- Transverse Wave:
- If the particles of the medium vibrate perpendicular to the direction of propagation of a wave, the wave is called a transverse wave.
- Wave on strings under tension, waves on the surface of the water are examples of transverse waves.
