The correct answer is: B. Polarisation.
Polarization is a property of transverse waves that describes the orientation of the wave’s electric field. In a transverse wave, the electric field is perpendicular to the direction of the wave’s motion. When a transverse wave is polarized, the electric field oscillates in a single direction.
Electromagnetic waves are transverse waves, and they can be polarized. This is evident in the phenomenon of polarization, which is the ability of electromagnetic waves to be restricted to a single plane of oscillation. This can be observed in the way that polarized sunglasses reduce glare from reflected light.
The other options are incorrect because they do not provide evidence that electromagnetic waves are transverse in nature.
- Reflection is the bouncing of a wave off of a surface. It does not depend on the wave’s polarization.
- Interference is the superposition of two or more waves. It can occur with both transverse and longitudinal waves.
- Diffraction is the bending of a wave as it passes through a narrow opening or around an obstacle. It can occur with both transverse and longitudinal waves.
