Physics 2.3 Demonstrate understanding of wave phenomena
Subject content
Revise your NCEA level one work about waves and light.
You may be assessed on the phenomena, concepts, and principles of the following topics:
- Light
You need to have an understanding of both qualitative and quantitative treatment of:- reflection in curved mirrors
- refraction through lenses
- refraction at a plane boundary
- total internal reflection and critical angle at a plane boundary.
- Waves
- reflection and refraction at a plane boundary including phase and wave parameter changes if applicable
- superposition of pulses
- diffraction
- 2-point source interference (qualitative)
- properties of electromagnetic waves (using the left-hand-side navigation, you will need to scroll down to Science trek and select EM waves).
You will need to know these relationships or formulae:
or
si so = f 2
or
n1 sinq1 = n1q2
v = fl
