Diffraction 1

What is diffraction?

Waves of HIGHER WAVELENGTH produce GREATER DIFFRACTION.

Since the RED light shows a higher diffraction, the RED light has a LARGER WAVELENGTH.
Further, this means that RED has a LOWER FREQUENCY than blue.

Huygens Principle
Explanation for Diffraction
Each point on a wave front can be considered to be a centre of disturbance for a new source of waves.

Important Notes

1. Narrower slits produce larger diffraction.

2. If RED light is used: (red and black bands observed)

3.If BLUE light is used: (blue and black bands observed)
