What is the colour that comes to the base of the prism if composite yellow light is passed through it. Answer is Green
1. What is the colour that comes to the base of the prism if composite yellow light is passed through it
Answer is : Green
You should know three things here
1. Yellow light is composed of two primary colours Red and Green
2. When passing light through a prism the colours are splitted into VIBGYOR
3. Violet has more deflection and Red has least deflection
When yellow light is passed through a prism colour combinations of green and red will obtain and colour that has primary colour blue will not be there. So by passing yellow light through a Prism Red,Orange,Yellow,Green colours will be obtained. From the information Green will have more deflection through prism. So Green will be closer to the base.

Solution
This is a tricky question asked in PSC Beat Forest officer question paper. First you should understand the question. The question can be simplified as, a yellow light is passed through a prism, what is the colour close to the base(After splitting of yellow light)You should know three things here
1. Yellow light is composed of two primary colours Red and Green
2. When passing light through a prism the colours are splitted into VIBGYOR
3. Violet has more deflection and Red has least deflection
When yellow light is passed through a prism colour combinations of green and red will obtain and colour that has primary colour blue will not be there.
