How do we obtain a point source of light for experiment on reflection of light
Answers
Answer:
When light waves are incident on a smooth, flat surface, they reflect away from the surface at the same angle as they arrive. This tutorial explores the relationship between incident and reflected angles for a virtual sinusoidal light wave.
Explanation:
Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. The simplest example of visible light reflection is the surface of a smooth pool of water, where incident light is reflected in an orderly manner to produce a clear image of the scenery surrounding the pool. Throw a rock into the pool , and the water is perturbed to form waves, which disrupt the reflection by scattering the reflected light rays in all directions.
