Question

why spectrum is formed when white light is passed through a glass prism



brainlist for valid answer ✌✌​

Answer 1

Answer:

Hey mate white light is made up of seven colors.

The light waves of different colours vary in their frequency and wavelengths..

when the white light is made incident in the glass prism it undergoes refraction..

the prism splits the white light into a band of Colors..

the higher frequency which have lower wavelength travel slower but they refract more than lower frequency which have higher wavelength red light..

as same as other colour light waves bend with respect to the incident white light as they pass through the prism. ...

then the ray of different colors emerges alone and become distinct . this band of colored components of a light beam is called spectrum..

sequence of light according to their frequency and wavelength ..are VIBGYOR

Violet, Indigo, Blue, Green, Yellow, Orange and Red.

Answer 2

Answer:

When the light encounters a prism, it refracts, but each color refracts at a slightly different angle due to dispersion. When the light leaves theprism the colors are travelling at slightly different angles. View far enough away for the colors to separate, a little rainbow (or spectrum) is formed.

Actually a white light consist of combination of VIBGYOR forming a white light passing through a prism that why all happens ...

MARK AS BRAINLIST IF THIS HELPS U PLZZ

THANKS

HAVE A GUD DAY
