Activity 9.5 — Refraction through a Prism

NCERT Activity 9.5: Shine light through a triangular prism and observe how it bends at both surfaces, emerging deviated from its original path.

How To Perform

1

Shine Light

Direct a light ray at the first face of the prism.

2

First Refraction

Observe the ray bending toward the normal as it enters the glass.

3

Second Refraction

Watch the ray bend away from the normal as it exits the prism.

4

Angle of Deviation

Measure the angle between the original and deviated ray paths.

5

Classify

Define the angle of deviation in a prism.
