a repeating disturbance or movement that transfers energy through matter or space (waves carry energy WITHOUT transporting matter); they are produced by something that vibrates
these waves can ONLY travel through matter; the two types of mechanical waves are transverse waves and compressional waves
wave for which the matter in the medium moves back and forth at right angles to the direction the wave travels; has crests and troughs
a wave for which the matter in the medium moves back and forth along the direction that the wave travels (ex: sound waves)
the number of wavelengths that pass a fixed point each second; is expressed in hertz(Hz) As frequency increases, wavelength decreases
wave speed equation
speed=frequency(Hz) X wavelength
wave speed depends on the material it is traveling in and the temperature
a measure of the energy carried by a wave; the greater a wave's amplitude, the more energy it carries
amplitude in a compressional wave
related to how tightly the medium is pushed together at the compressions (the less dense the medium is aat the rarefactions, the more enefgy the wave carries)
amplitude of a transverse wave
the distance from the crest or trough to the rest position of the medium
the bending of waves around an obstacle; can also occur when waves pass through a narrow opening; the effects of diffraction are greatest when the wavelength is nearly the obstacle's size
a wave pattern that forms when waves of equal wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other; has points called nodes that do not move
