How can you combine separated lights by a prism?

Answer 1

Mechanism of Traveling of Light:

It might be a Common knowledge that Light travels with different velocity in different mediums viz. Solid, Liquid or Gas.

This is mainly because of the fact that different mediums have different Optical Density and when Light enters any Specific medium a part of the incident light will in fact be scattered by the particles of that medium. This depends on the fact that how tightly the molecules or Dispersed Particles are held together which is highest in case of Solids and Least in case of Gases.

Now we have Understood that Light travels with varying velocities in any media. This property of Light is Known as 'Refraction'.

For example, a light ray will refract as it enters and leaves glass, Its wavelengthincreases or decreases.

Traveling of Light through Prism:

A prism is a transparent solid usually made of glass or such transparent compounds bounded by three rectangular faces and two triangular faces.

So when a Polychromatic Ray of Light is passed through it, the different wavelengths of light suffer varying degree of refraction and Ultimately If a Screen is Placed behind the Prism the different constituent components of the light can be Obtained.

i.e., Polychromatic Light is divided into ----> V I B G Y O R

V= Violet

I= Indigo

B= Blue

G= Green

Y= Yellow

O= Orange

R= Red

Answer 2

You can combine separated lights by a prism through a process known as dispersion. When white light passes through a prism, it is separated into different colors due to the different wavelengths of each color. To combine the separated lights, you would need to direct the individual colors back through the prism at the correct angle to recombine them into white light.

Answer 3

Add a second prism to combine the light.

The first prism separates the light and the second prism combines the light.

Answer 4

by passing it through another prism that can convert light to combine

Answer 5

just put the second prism just in the opposite direction as of the prism

Answer 6

just put the second prism just in the opposite direction as of the prism

Answer 7

A prism seperates light into different colours, when White light passes through the spectrum giving you its colours, red,orange,yellow,green,blue,indigo and violet.

Answer 8

It uses the fact that refraction works differently for different frequencies - some frequencies refract more than others.
