Term Definition
Compressional Wave mechanical wave that causes particles in matter to move back and forth along the direction the wave travels
Diffraction bending of the waves around the object
Electromagnetic Spectrum complete range of electromagnetic waves 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 number of wavelengths that pass a given point in one second, measured in hertz
Infrared Waves electromagnetic waves with wavelengths 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 states than an angle the incoming wave makes with the normal to the reflecting surface equals the angle the reflected wave makes with the surface.
Pitch human perception of the frequency of sound
Refraction change in the direction of a wave when it changes speed as it travels from one material into another
Reverberation repeated echoes of sound waves
Transverse Wave mechanical wave that causes particle in matter to move at right angles to the direction the waves travel.
Ultraviolet Waves electromagnetic waves with wavelengths between about 400 billionths and 10 billionths of meter
Wave disturbance that moves through matter and space carries energy
Wavelength distance between one point on a wave and the nearest point moving with the same speed and direction.
