You saw in the previous activity that waves can diffract when they interact with an appropriately sized aperture. Light, being a wave, is capable of doing the same thing. Sketch what you predict the pattern would look like on a screen placed in the path of a light wave if: $(3$ marks $$ A$)$

Light hits screen unobstructed without passing through aperture:

Light hits screen after passing through a single narrow aperture $($single slit$)$:

Light hits screen after passing through two, closely spaced, narrow apertures $($double slit$)$:
