A wave is a disturbance that moves through matter and space and carries energy.
The frequency of a wave is the number of wavelengths that pass by a point each second.
The amount of energy that a wave carries past a certain area each second is the intensity of the sound.
Electromagnetic waves with wavelengths between about 400 billionths and 10 billionths of a meter are ultraviolet waves .
The law of reflection is the angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal.
pitch is the human perception of the frequency of sound.
A transverse wave causes particles in matter to move back and forth at right angles to the direction in which the wave travels.
The distance between one point on a wave and the nearest point moving with the same speed and direction is the wavelength .
A compressional wave causes particles in matter to move back and forth along the same direction in which the wave travels.
Repeated echoes are called reverberation .
electromagnetic waves are waves that can travel through matter or through empty space.
refraction is the change in direction of a wave when it changes speed as it travels from one material to another.
infrared waves have wavelengths between 0.001 meters and 700 billionths of a meter.
The electromagnetic spectrum is the complete range of electromagnetic wave frequencies and wavelengths.
Waves can change direction by diffraction which is bending of waves around an object.
