  3. Light waves can be polarized

  4. Light waves can be diffracted

Solution

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.
