Which Colour of white light has the highest speed in vacuum?
So according to equation (1) velocity of light is directly proportional to the wavelength. So violet color has minimum velocity of light and red color has maximum velocity of light when it passes through the glass. Hence the red color of white light travels fastest in the glass. Hence option (A) is the correct answer.
Which light has maximum velocity?
Red light having maximum wavelength travels fastest.
What causes dispersion of white light?
Dispersion occurs due to the different degrees of refraction experienced by different colours of light. This difference in the extent of bending of different colours of light results in the dispersion of white light into its constituent colours as they emerge from a prism.
Why do different components of white light split up into spectrum?
This splitting of the light ray occurs because of the different angles of bending for each colour. Hence, each colour while passing through the prism bends at different angles with respect to the incident beam. This gives rise to the formation of the colour spectrum.
Why do different components of white light split up into spectrum while passing through glass prism Class 10?
This splitting of the light ray occurs because of the different angles of bending of each colour. Hence each colour passing through the prism bends at different angles with the respect to the incident beam. This gives rise to the formation of the colour spectrum.
Why does light split into spectrum?
White light can be split up to form a spectrum using a prism. The shorter the wavelength of the light, the more it is refracted. As a result, red light is refracted the least and violet light is refracted the most – causing the coloured light to spread out to form a spectrum.
Why do different components of white light deviate through different angles?
It occurs because light is made up of seven different colors or wavelengths and thus behave differently upon hitting the prism. It is such that the refractive index of each wavelength varies which splits the single white light, causing dispersion.
What is meant by spectrum of white light?
When white light comes out of the prism, light is spread in a fan shaped beam. This fan shaped beam is termed as a spectrum. Light is said to be dispersed into a spectrum consisting of violet, indigo, blue, green, yellow, orange and red.
How can we recombine the components of white light?
The coloured pattern VIBGYOR formed by a prism by splitting the incident white light is called a spectrum. By having two prisms, inverted to each other, one can recombine the light to get white light again.
When white light is passed through a triangular prism which component Colour of white light deviates the most and why?
Answer. White light is composed of light of different wavelengths (colors) i.e. violet, indigo, blue, green, yellow and red. The color red therefore deviates the least since it has maximum wavelength and color violet deviates the most since it has the least wavelength.
Which Colour of white light is least deviated?
red
