when light refracts by prism into 7 colors .each color bends because it has diffrent frequncy and wavelength.?

Question

its true "i know that. but how(exactly) this happens . how each color bend in different angle since all colors will still have the same speed in prism?? plz help . source adress wich have animation would help too? thank you.

Answer 1

When light passes out of a vacuum into another medium, it is bent a tiny bit -- it refracts. The strength of the bending depends on the index of refraction of the material. The index of refraction of any medium depends on the frequency of the incident radiation. That is because the speed of light in a dense medium depends on the wavelength (frequency) of the light. In a prism, the higher the frequency (and the shorter the wavelength), the more bending it does. That's why the red tones are on the outside of a rainbow, and the blue and indigo on the inside.

Answer 2

you could try wikipedia.org or answers.com to get some idea and links on animated details of light dispersion in the prism.

and each light wave in a spectrum has its own specific frequencies!
and since velocity of wave(~3x10^8 for EM waves) = frequency x wavelength for any wave. In entering a glass, the light waves refract since glass is an optically more dense medium than air.In refraction process, the angles that are refracted are different according to the respective wavelengths of each colour.BUT, the frequency of each coloured light does not change.
in doing so, the speed of each respective coloured light slows in different manner in the glass prism. hence, when the lights emerges out at the other face of the prism , it is technically and practically divided into the spectrum.

Answer 3

One step missed, they slow down in the prism during refraction, and each slows a different amount.

Answer 4

This structure of a prism is such that it disperses white gentle into component shades. Rain drops disperse gentle by entire inner mirrored image (TIR) thereby generating rainbow. Our eye lens isn't of the shape that could disperse gentle. Eye lens varieties a pointy, actual and inverted photo on the retina, the retina communicates this photo to the mind by the optic nerve. wish that facilitates :)

Answer 5

The lower frequency light (RED bends more than higher freq. light (blue) . The higher the frequency the less the bend. The higher the freq,The higher the energy thus less bending.

Answer 6

It's not true that the frequency changes. The speed and the wavelength change.
