wavelength
law of reflection

1. the complete range of electromagnetic wave frequencies and wavelengths
2. waves with wavelengths between one thousandth and 700 billionths of a meter
3. causes particles in matter to move back and forth along the same direction in which the wave travels
4. the distance between one point on a wave and the nearest point moving with the same speed and direction
5. the angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal
6. the amount of energy that a wave carries past a certain area each second
7. the human perception of the frequency of sound
