OUTCOME
By the end of this lesson you will be able to describe and explain young's double slit interference and how this phenomenon supports the theory of light as a wave
Interference patterns can be observed when two slits are made in a card and light shines through. The patterns correlate to wave interference from two sources
LEARNING TASKS

Use your two source interference pattern to explain why we see a stripy pattern with two slits of light
