Refraction, Huygens,Parallel Plate, Triangular Prism

The critical angle of a material is the angle of incidence for which the angle of refraction is:

• 0°

• 30°

• 45°

• 90°

• 180°

The principle underlying fiber optics is:

• diffraction

• dispersion

• interference

• polarization

• total internal reflection
