 What is a wave? A method of transferring energy from one place to another w/o the transfer of matter What is energy? The ABILITY to do work What is a transverse wave? a WAVE in which the medium vibrates PERPENDICULAR to the direction the wave energy travels What is a medium? Material or substance that the wave energy travels What is reflection Bouncing of a wave off of the boundary between 2 different media (plural medium) What is dissipation? Decrease in energy of a wave, as it travels further and further from the source. What is Refraction? Bending of a wave as it passes from one medium to another b/c of a change in speed What is a Boundary point of contact between 2 different media What is a wavelength? distance from one point on a wave to the same point on the next consecutive wave What is a crest? Upper displacement of the particles of the medium away from equilibrium What is a trough? Downward displacement of the particles of the medium away from equilibrium What is the equation for frequency? # of wavelength ÷ unit of time What is amplitude? maximum displacement of the particles of the medium away from equilibrium What is color? The human interpretation of the frequency of a light wave (Type of light) All of the frequencies of the white light are absprbed except ________ frequency which is reflected. Brightness/dimness human interpretation of the amplitude of a light wave What is a longtidunal wave? wave in which particles of the medium vibrate PARALLEL to the direction which the wave energy travels What is a compression? The are of longitudinal wave in which the particles of the medium are more dense then at Xo What is a rarefaction? The are of a longitudinal wave in which the particles are less dense then at Xo Pitch- human interpretation of a sound wave Loudness/Quietness human interpretation of a sound wave interference-- when 2 or more similar waves pass through the same medium at the same time, the resulting wave form is the additive sum of each of the waves
