E. MATERIAL



If the medium through which the light is uniform, how

propagation of light? To investigate how light propagates.

Law of reflection states that the angle of incidence equal to

the angle reflection. Each light reflected, if reflected from a

mirror, aluminum foil, or the month following the laws of

reflection..

Refraction of light is the bending of light waves caused by a

change in the speed of light waves such as light waves propagate

from one substance to another substance.

The relationship among object distance, shadow distance and

focal length on the concave mirrors and convex mirrors, can be

expressed by the following equations.
