| Front | What is the critical angle? |
| Back | Critical angle = the angle of incidence at the boundary between 2 media that will produce an angle of refraction of 90 degrees |
| Front | How does an electron gun work? |
| Back | Electrons are emitted from the hot wire/filamentThere is a large p.d. between the filament and an anode (filament acts as cathode)Freed electrons are accelerated towards the anodeThey pass through a hole/gap in the anode |
| Front | Derive the second ‘suvat’ equation/equations of motion without v |
