Light Waves II
Performance Objectives
Students should be able to;
- Measure angels of incidence and refraction and hence deduce a value for the refractive index of a given material.
- Explain the meaning of critical angle and total internal reflection stating the conditions under which they occur.
- Establish the relationship between critical angle and refractive index and apply it to the solution of simple problems
- Trace light rays through a triangular prism and obtain graphically the value of the angle of minimum deviation.
