~LESSON 2 ~
3 laws of light.
1. Light travels in a straight line
As shown by the shadow created by the two cards.

2. The farther you are from the light source the dimmer the light (inverse square law)
As shown by the diminishing intensity of the light through the gap in the cards as it travels towards the mirror, and also the diminishing intensity of the light beam bouncing away from the mirror.

3. Angle of reflection = Angle of incidence
As shown by the right angle created by the light beam hitting the mirror and the beam bouncing off from the mirror. We included a small amount of reflection in the mirror so you could see how the angle created by the beam and its reflection are equal to the refracted beam and its reflection.
