Why is white light dispersed by a glass prism?
When white light(composite light) consisting of various colors is passed through a prism, light of different colors will be deviated through different angles. Since the deviation is related to refractive index and refractive index to the color of light the deviation produced for different colors are different for same prism.That is the refractive indices are different for the various colors and this difference in the refractive indices is responsible for dispersion.
Why is the constant deviation spectrometer named so?
It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
Can light be separated into colors?
Using a prism a beam of light can generally be defracted into the different colors that make up that beam of light. The visible spectrum of red, orange, yellow, green, blue, indigo, and violet can often be seen.
What is the differnce between refraction and reflection?
reflection is when it is reflected; it bounces of the surface while refraction is when it is bent but not reflected
When blue light goes through a prism what happens?
Blue light enters the prism and is refracted (bent) by the glass and emerges as blue light on the other side. Blue light is bent (refracted) most due to its slow(er) speed than say Red light which is faster and has a longer wavelength. Newton did an experiment like this and concluded that white light was made up of different colours of light together. Shine a white light through a prism and it will emerge as all the colours of the rainbow. Blue light is unchanged as it consists only of blue light Answered by Chris Banks.
What phenomenon cause color of visible light to be separate by a prism?
Refraction is the phenomenon causes colors of visible light to be separated by a prism.
What can be separated with a prism?
White light.
How do you get the same ray of light after passing through the prisms?
after the light passes through the prism, the light is technically still the same just separated into different energy levels or colors. if you want to achieve the "white" light that entered the prism again, you can place another prism in front of the colored light and it should combine and create the "white" light again.
Can white light be separated only by a prism?
yes.
What phenomenon causes of visible light to be separated by a prism?
Dispersion
Why do you get a raindow when you shine light through a prism?
because the 7 colors which form the white light is separated as their speed is not the same in the prism.
How can the colors that make up a white light be separated?
by use of a prism
What happens when a ray of light is shone into a prism?
The various frequencies are separated.
How is light separated into a spctrum?
With a prism. Light striking the prism is of different wavelenghts. These corrospond to the thickness of the wedge splitting the colors out of the source. They can be put back together with another prism.
What is the process in which white light is separated into the colors of the rainbow?
In optics, a prism refracts incoming light.
Howis light separated into spectrum?
This is normally done by passing it through a prism.
Which colour of White light is scattered the least and why?
White light is light that has not been scattered. Shine a beam of white light through a prism, and the light is separated into 'rainbow' colours. Sunlight shining through raindrops is the cause of a rainbow appearing in the sky.
