It is because rays of different colours have different wavelengths. Waves with shorter wave lengths undergo less refraction.

What bends light rays?

A prism bends light rays. White light is made up of many different wave lengths of light. A prism bends each wave length a different amount, that is why different colors are produced from the output side of a prism.


What is splitting of light rays called?

The splitting of light rays into different colors is called dispersion. This occurs when light rays pass through a prism or other refractive medium, causing the different wavelengths of light to refract at different angles and separate into the colors of the rainbow.


How do you separate sun light rays?

a prism will do that


How do you separate the rays in a light beam to make a rainbow?

To separate the rays in a light beam and make a rainbow, you can use a prism or water droplets in the atmosphere. When light enters a prism, it is refracted at different angles depending on its wavelength, causing the different colors in the light spectrum to separate. Similarly, when sunlight passes through water droplets in the air, it is refracted and dispersed, creating a rainbow.


Why you use triangular prism why cant you use rectangular prism in diffraction?

bcoz in triangular prism, sides are not parallel so rays will deflect but in rectangular prism sides are parallel so rays won't deflect instead they will pass straight.


What does a prism do to light rays?

A prism refracts light rays, causing them to bend and separate into different colors. This effect is called dispersion, where each color of light is refracted by a slightly different angle due to its wavelength, resulting in a rainbow-like spectrum.


Can a prism transmit rays at all angle of incident?

yes


How does a prism turn colored light into white light?

White light is not a single wavelength. Our eyes perceive three major colors, and fabricate "white" from that. The speed of light in materials is a function of wavelength, and so the different wavelengths of light are bent slightly differently upon entering the material of the prism, and bent again slightly differently upon exiting. The net is the violet light is spread one way, and the red a different way, with the other colors arranged in between. So Lets Say: --------------------------- <= Ultra Violet Light>>>|Prism| |Spectrum| --------------------------- <= Infared U & I are the to rays coming out of the prism from the white light


Why light rays does not bend towards thicker part while passing through prsm?

When light rays pass through a prism, they refract or bend due to the change in speed as they move from one medium to another. This bending is caused by the difference in the refractive index of the prism material compared to the surrounding medium. The direction of bending is determined by the angle at which the light enters and emerges from the prism, according to Snell's Law. The thickness of the prism itself does not play a significant role in the bending of light rays within the prism.


What happens when light passes through two erect prisms?

When light passes through two erect prisms, the light rays are refracted twice - once when entering the first prism and again when exiting the second prism. This causes the light rays to change direction twice, leading to further dispersion of the different wavelengths.


Why does in a prism light bend towards the base?

Light bends towards the base of a prism due to refraction, which occurs when light travels from one medium to another with a different optical density. As light enters the prism, it slows down and changes direction, causing it to bend towards the base. This bending of light rays allows prisms to separate white light into different colors.


Who used a prism to understand light rays?

Sir Isaac Newton used a prism to show that white light is made up of different colors of light through a process called dispersion. He demonstrated that when white light passes through a prism, it separates into a spectrum of colors known as the visible light spectrum.
