When a light ray enters a prism it emits different colours whereas a glass does not emit colours.Why?

Answer 1

speeds of different colours of light are different inside the glass
in prism each colour travels different distances unless in a rectangled glass slab

Answer 2

Actually, glass can be used as a prism, and prisms are commonly made of glass. Prisms work by taking advantage of the fact that the index of refraction varies with wavelength. This allows light of different wavelengths to be bent by different degrees according to the law of refraction. Though if you just use any ol' chunk of glass, you probably won't notice the effect if the incident beam is too wide or if the glass surfaces aren't sufficiently polished or smooth.

Answer 3

A prism allows light to travel from one medium into another at an angle. While this phenomenon may exist to a slight extent in a common drinking glass, it is not enough to produce a rainbow.
Refraction is responsible for rainbows and for the splitting of white light into a rainbow-spectrum as it passes through a glass prism. Glass has a higher refractive index than air and the different frequencies of light travel at different speeds (dispersion), causing them to be refracted at different angles, so that you can see them. The different frequencies correspond to different colors observed.

Answer 4

the refraction suffered bywhite light when it passes through the prism separates the different wavelengths or colours,as glass has different refractive index for different wavelengthspresent in the white light.

Answer 5

The moon would not emit easy or warmth. The moon, merely like Earth, gets all of it's easy and warmth from the sunlight. the sunshine reflecting off of the moon could make a small quantity of heat. because of the fact the moon has no environment, it can't seize the warmth the way Earth does, making it chilly.
