Doppler effect |
2 |
|
|
|
11.2.5 |
Solve problems on the Doppler effect for electromagnetic waves using the approximation Δf=vf/c. Students should appreciate tha the approximation may be used only when v < < c. |

|
|
11.5.1 |
Describe what is meant by polarized light. |
|
|
|
|
11.5.2 |
Describe polarization by reflection. This may be illustrated using light or microwaves. The use of polarized sunglasses should be included. |
|
|
