heya!
here's your answer!


➡ firstly , we need to know why a spectrum is formed and how.. before knowing the colours in it and further explanation.:-
hence it's this:-

➡ 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 

❇ the colour with highest wavelength is red which is the first colour of the spectrum and with the colour with the lowest wavelength is violet which is at the last of the spectrum
that's your answer.
