waves

TermDefinition
compressional wave mechanical wave that causes particles in matter to move back and forth along the direction the wave travels
diffraction bending of waves around an object
electromagnetic spectrum complet range of electromagnetic wave frequencies and wavelength
electromagnetic waves waves that can travel through matter or empty space, includes radio waves, infuriated waves etc.
frequency number of wavelengths that pass a given point in one second measured in hertz
infrared waves electromagnetic waves with the 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 states that the 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 direction of a wave when it changes speed as it travels from one material into another
reverberation repeated echoes of sound waves
transverse waves mechanical waves that cause particles in matter to move at a right angle to the direction the wave travels
ultraviolet waves electromagnetic waves with wavelength between about 400 billionths an 10 billionths of a meter
wave disturbance that moves through matter and space and carries energy
wavelength distance between one point on a wave and the nearest point moving with the same speed and direction
