Question

Which of the following statements does indicate that light waves are transverse?

• A. Light waves can travel in vacuum
• B. Light waves show interference
• C. Light waves can be polarized
• D. Light waves can be diffracted

Answer 1

The correct option is C

Light waves can be polarized

The explanation for the correct options:

Option C is correct:

1. Polarization is a property applying to transverse waves that specify the geometrical orientation of the oscillations.
2. Polarisation of light: Polarisation is a process in which vibrations occur only in a single plane.
3. In the longitudinal direction of vibration of the particle is in the direction of the propagation of the wave.
4. While in a transverse wave, vibrations are perpendicular to the direction of propagation.
5. Therefore, longitudinal vibration passes through the polariser.
6. The diagram of the polarisation of light is given below:-

Option A:

1. Only transverse waves can travel through a vacuum, longitudinal waves required a medium for propagation.

The explanation for the incorrect option:

Option B:

1. Interference can be observed in both longitudinal and transverse waves.

Option D:

1. Diffraction can be observed in both longitudinal and transverse waves.

Hence, option A, C are correct options.
