Question

A white light OP passes through a prism, as such its components get refracted, as shown in the following diagram.
The components A, B, C and D represent respectively.

• A. Red, green, yellow, violet
• B. Green, yellow, blue, orange
• C. Blue, green, yellow, red
• D. Red, yellow, green, blue

Answer 1

The correct option is D Red, yellow, green, blue

Wavelength increasing order is:

$blue<green<yellow<red$

Refractive index will follow reverse order as of wavelength.

Deviation order will be:

$blue>green>yellow>red$

$\delta =(\mu -1)\times A$
