Question

what happen when the light rays enter in a triangular glass prism point wise answer

Answer 1

it splites into seven different colours .

Answer 2

heya!
here's your answer!

➡yes , when a beam of white light is passed through a hollow prism .. it refracts to produce the spectrum of 7 colours .

➡ the spectrum includes
◾V- violet \
◾I - indigo \
◾b - blue \
◾g - green l ⏩ this is called Vibgyor
◾y - yellow /
◾o - orange/
◾r - red /

➡ this happens because the two faces of the prism act together like a glass slab .. which does not reflect light

➡ rather refracts it - now if you pass a spectrum through the prism - a clear beam of white light will come out from it

➡ but you must be thinking why this happens?
well .. this happens because when you combine these 7 colours can, white will be formed

➡ we're able to see the layers of the colours Because all the colours have different wavelengths and refractive indexes

➡ the glass slab gives spectrum too but it's not seen because the glass slab is too slender and narrow .. naked eyes can't see it
