compressional waves mechanical wave that causes particles in matter to move back in forth along the direction the wave travels
diffraction waves can change direction which is the bending of waves around an object.
electromagnetic spectrum complete range of electromagnetic wave frequencies and wavelength
electromagnetic waves waves that can travel through matter or empty space includes radio waves in fared waves visible light waves ultraviolet waves x rays and gamma rays
frequency The frequency of a wave is the number of wave lengths that pass by a point each second.
infrared waves electromagnetic waves with wavelength between about one thousandth of a meter and 700 billionths of a meter
intensity amount of energy a wave carries past a certain area each second
law of reflection According to law of fraction the angles that the incoming wave make the normal equals the angle that the outgoing wave makes with the normal.
pitch as it relates to sound
refraction Refraction is the change in direction of a wave when it changes speed as it travels from one material to another.
reverberation repeats echoes of sound sound waves
transverse wave A transverse wave causes particles in matter to move back and forth at right angles to the direction in which the wave travels.
ultraviolet wave electromagnetic waves with wavelength between about 400 billionth and 10 billionths of a meter
wave A wave is a disturbance that moves through matter or space.
wavelength The distance between one point on a wave and the nearest point moving with the same speed and direction is the wavelength.
