Question

A bright white light underwater is collimated and directed upon a prism. What range of colors does one see emerging?

Short answer

The range of colors one sees emerging is in VIBGYOR order.

Step-by-step solution

Definition of prism

A prism is a transparent object, such as glass or plastic, that has at least two flat surfaces that make an acute angle.

The range of colors we see emerging upon a prism

As white light goes through a prism due to rarefaction, it is split into seven distinct hues. Each color has a different wavelength, thus they span different distances, which is why they are spliced into seven distinct colors.

VIBGYOR order has seven different colors.

V-VIOLET

I-INDIGO

B-BLUE

G-GREEN

Y-YELLOW

O-ORANGE

R-RED

Therefore, when white light passes through a prism, it is divided into seven different hues due to refraction.
