- 1ReflectionWhen a wave hits a surface, any part of the wave that cannot pass through the surface bounces back.
- 2example Reflectionwhen you see yourself in the mirror, you used reflected light to see yourself.
- 3law of reflection:the angle of incidence equals the angle of reflection
- 41. Incoming wavea wave moving toward the surface at an angle.
- 52. Angle of incidencethe angle between the incoming wave and the normal.
- 63. Normala line perpendicular to the surface a the point where reflection occurs.
- 74. Angle of reflectionthe angle between the reflected wave and the normal
- 85. Reflected wavea wave bouncing off the surface at an angle
- 9Refractionthe bending of waves due to a change in speed.
- 10causes the wave to bend● When a wave enters a new medium at an angle, one side of the wave changes speed before the other side
- 11● Bending occursbecause different parts of the wave travel at different speeds
- 12● No bending occurs ifa wave enters a new medium at a right angle.
- 13example Refractionwhen you are on a skateboard and you change from the sidewalk to the grass the skateboard is going to slow down.
