### Step-by-Step Solution #### Part (a) **(i) What is meant by diffraction of light?** Diffraction of light refers to the phenomenon where light waves bend around obstacles or spread out after passing through narrow openings. This bending allows light to illuminate regions that would otherwise be in shadow, demonstrating that light behaves as a wave. ...
