Problem
A physics teacher wants to teach her class about wave-particle duality.
(a) State what is meant by the term *wave-particle duality*. [1]
(b) Suggest a demonstration the teacher could use to show that light behaves like
- i waves. [1]
- ii particles. [1]
(c) In order to show her students that particles behave like waves, the teacher chooses to show her students a demonstration of electron diffraction by a crystal of graphite. Outline briefly the main features of her demonstration. [2]
