Waves
Term | Definition |
---|---|
wave | a disturbance that moves through matter or space |
transverse wave | causes particles in matter to move back and fourth at right angles to the direction in which the waves travel |
compressional wave | causes particles in matter to move back and fourth along the same direction in which the waves travel |
wavelength | the difference between one point on a wave and the nearest point moving with the same speed and direction is the wavelength |
frequency | the number of wavelengths that pass by a point each second |
law of reflection | the angle that the incoming wave wave makes with the normal equals the angle that the outgoing wave makes with the normal |
diffraction | the change in direction of a wave when it changes speed as it travels from one material to another |
