Question

What happens when light goes through a prism ?

Answer 1

Hint: A glass prism is a transparent object with two triangular ends and three rectangular sides. Light is made up of a variety of component colors of varying wavelengths. A light ray deviates from its direction only when it switches the medium of propagation, and a white light travels in a straight line.

Complete answer:
Light bends as it passes through a prism. The various colors that make up light become separated as a result. This is due to the fact that each color has its own wavelength, which bends at a different angle. Prism merely serves as a conduit for the dispersion of light in the seven primary colors. As light strikes the prism, refraction occurs. These deviated colors have different wavelengths and frequencies, and they deviate differently at different angles due to the prism's velocity difference.

When a beam of light travels through a glass prism, it is refracted both inside and outside the prism. The emergent ray and incident ray aren't parallel since the refracting surfaces aren't parallel. As a beam of light passes through a prism, it is deviated in this situation. The light is divided into its component colors - red, orange, yellow, green, blue, and violet - as it passes through the prism. Dispersion is the division of visible light into its various colors.

So we can conclude that when light goes through a prism, dispersion occurs.

Note: Do not confuse white light with monochromatic light when answering these types of questions. Monochromatic light is described as light with only one wavelength or frequency. White light is made up of a range of colors of varying wavelengths or frequencies.
