Question

What proves that light is a transverse wave?
A.) Polarization
B.) Reflection
C.) Refraction
D.) Interference

Answer 1

Hint: In order to deal with this question first we will define transverse waves then we will proceed further by using the property of light and the property of transverse waves. We will compare the properties of light and the transverse wave in order to find the property out of the given options which proves the statement.

Complete step by step answer:

A transverse wave is a moving wave made up of oscillations that occur perpendicular to the energy transfer direction.
The purpose of the polarization of light is to distinguish only one of these infinite planes, with regard to either the electrical field or the magnetic field (in either case, only one of these infinite possibilities would correspond). And we need any physical part in a light wave which can be used to signify a certain vibrational plane. Electric and magnetic fields do the job.
Hence, Transverse nature is a necessary criterion for polarising light.
So, the correct answer is option A.

Note: Reflection, refraction and the interference is the optical property of light. Reflection and refraction are the boundary effects of waves associated with a beam of light changing its direction. Reflection happens as rays of light from a membrane bounce back. Refraction is the change in direction of waves of light that occurs when waves travel with different refractive index from one medium to another. Wave interference is the phenomenon that occurs when two waves come together on the same medium.
