Waves 2

Wave A disturbance that moves through matter or space
Compressional wave Causes particles in matter to move back and forth along the same direction
Diffraction Bending of waves around an object
Electromagnetic spectrum Complete range of electromagnetic wave frequencies and wavelengths
Electromagnetic waves Waves that can travel through matter or empty space, includes radio waves, infrared waves visible light waves, ultraviolet waves, X rays, and gamma rays
Frequency The number of wavelengths that pass by a point each second
Infrared Waves Electromagnetic waves with wavelengths between about one thousandth of a meter and 700 billionth of a meter.
Intensity Amount of energy a wave carries past a certain area each second.
Law of reflection The angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal.
Pitch As the amplitude (energy) decreases the sound gets softer
Refraction The change in direction of wave when it changes speed as it travels from one material to another.
Reverberation Repeated echoes of sound waves.
Transverse wave Causes particles in matter to move back and forth at right angles
Ultraviolet waves Electromagnetic waves with wavelengths between about 400 billionth and 10 billionth of a meter.
wavelength The distance between one point on a wave and nearest point moving with the same speed and direction
