Question

Now consider a beam of white light that enters a prism. Which one of the following statements is correct concerning the light exiting the prism (the outgoing light)?

The outgoing light is separated into the colours of the rainbow, with the red light bent the most.

The outgoing light is a beam of white light.    

The outgoing light is separated into the colours of the rainbow, with the violet light bent the most.

Answer 1

when a white light enters the prism

we will observe the out going light is separated into the colours of the rainbow so that

the deviation of the red light is less than the deviation of the voilet colour or

the violet colour bent is more than the red colour , the mean deviation wiil be for yellow colout

that means the angle of deviation for voilet colour is more than red colour

so the answer is The outgoing light is separated into the colours of the rainbow, with the violet light bent the most.
