Task 1

Find out how the interference pattern changes when the wavelength increases.

The separation between the antinodal and nodal lines increases as the wavelength increases.

Task 2

Find out how the interference pattern changes when the source separation increases.

The separation between the antinodal and nodal lines decreases as the source separation increases.

Instruction:

Vary the wavelength of the wave and the source separation.

Observe the interference pattern formed.
