Hint: To understand the propagation of light waves, Huygens's principle is used. Every point on the wave here acts as the source of the next spherical front of the wave. We get the new wave formed by the propagation of the wave if we draw a line joining the wave fronts.
Complete answer:
The primary wave front is called the wave front, which is used as the source for the spherical wave front. And the new wave produced after any moment is called the secondary wave front. This secondary wave now acts as the front of the primary wave, the next set of secondary fronts of the wave, etc. The propagation of both linear and spherical waves might be explained by this law.
Initially, the principles of Huygens might explain the laws of reflection and refraction. But the rectilinear couldn't do that,
Light propagation, which is also known as diffraction and interference, deals with the bending of light. Fresnel later showed, however, that the principle of Huygens could explain the behaviour of light due to diffraction and interference with slight changes. Therefore, clearly, the principles of Huygens could explain the properties of light such as reflection, reflection, diffraction and interference from the given option. Only the Photoelectric effect is left out of the given options.
So, the options (A), (B), (C), and (D) are correct.
Note:
The secondary waves which are formed always travel in the forward direction only. Also note that photoelectric effect is explained with the dual nature of waves. The others, however, talk of only the wave nature of the light.
