Question
Which phenomenon illustrates the nature of light waves ?
(A) Interference
(B) Diffraction
(C) Polarization
(D) None of the above
Solution
All of the options (A) Interference, (B) Diffraction, and (C) Polarization illustrate the nature of light waves.
(A) Interference: This phenomenon occurs when two or more light waves superpose to form a resultant wave of greater, lower, or the same amplitude. Constructive interference occurs when the phase difference between the waves is a multiple of two π, whereas destructive interference occurs when the difference is an odd multiple of π. This shows the wave nature of light.
(B) Diffraction: This is the bending of light waves around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle. This is a property exclusive to waves, hence it shows the wave nature of light.
(C) Polarization: This is a property of waves that can oscillate with more than one orientation. Electromagnetic waves such as light exhibit polarization, and this is another proof of the wave nature of light.
So, the correct answer is not (D) None of the above. Instead, all of the given options (A, B, and C) illustrate the nature of light waves.
