Light as a Wave: Reflection, Diffraction, Polarization, Scattering, and Absorption
|
| Reflection of Light |
The angle of incidence equals the angle of reflection. |
| Diffraction of Light |
Diffraction of red and green light by patterns on a diffraction plate is shown. You can use the ruler in the background of each slide showing diffraction by a particular pattern to verify that in each case red light is diffracted more than green light. |
| Polarization of Light |
The effect of crossed and uncrossed polarizers on a light beam is demonstrated. |
| Scattering and Absorption of Light |
The effects of passing light through a colloidal suspension of milk in water and through a solution of copper sulfate are shown. |
The following demonstrations illustrate reflection, diffraction, polarization, scattering, and absorption of light.
