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
