What Happens When White Light Passes Through A Prism

Light is refracted when it enters the prism and each colour is refracted by a.

Prism only acts as a medium for the separation of the seven colors. Dispersion of white light by a glass prism as shown in the image given above the prism has split the incident white light into a band of colors. When light passes through a prism the light bends. When white light is made to pass through a prism a spectrum of seven colors is formed which shows that white light is a mixture of seven different colors.

He found that if a beam of white light is passed through glass prism then it will split in to seven colours. White light refracts when it passes through a prism. The white light is separated into its component colors red orange yellow green blue and violet. White light can be split up into a spectrum of these colours using a prism a triangular block of glass or perspex.

The various colors those are seen through prism are arranged in order. The angle between two lateral faces of a prism is known as the angle of the prism. The separation of visible light into its different colors is known as dispersion. This happens because each color has a particular wavelength and each wavelength bends at a different angle.

Visible light also known as white light consists of a collection of component colors. Since the wavelength of different components of light is different and the frequency is constant each component gets deviated by a different angle due to the difference in velocity in the glass medium. Isaac newton found that when a beam of light is passed throuh a glass prism the white light breaks into constituent colors i e the colors of the rainbow. Each wavelength refracts at a different angle and the emergent light forms a rainbow.

White light disperses into its constituent colors as it passes through a prism and we therefore. This order is named as vibgyor. This phenomenon of splitting up of white light into its constituent colors is called dispersion. The separation of visible light into its different colors is known as dispersion.

These colors are often observed as light passes through a triangular prism. These colours are red orange yellow green blue indigo and violet vibgyor. As a result the different colors that make up white light become separated. When light falls on the glass prism refraction takes place.
