Ch 15 P2 Test Review

Chapter 15 part 2 portion of huge test on 5/14/14

QuestionAnswer
what is the amplitude of a transverse wave the maximum distance the particles in a medium move from their rest position as the wave passes
what does a larger amplitude mean there is more energy
what does the amplitude of a longitudinal wave depend on the distance between particles in the compressions and rarefactions
what happens when the amplitude of a longitudinal wave increases the particles in the medium get closer together in the compressions and farther apart in the rarefactions
what is wavelength the distance between crest to crest or trough to trough
what is the frequency of a wave the number of wavelengths that pass by a point each second
what SI unit is frequency measured in and what is its abbreviation hertz (Hz)
what is the frequency of a wave (not wavelengths) it is the same as the number of vibrations the vibrating object makes each second
what happens when the frequency of a wave increases the length decreases
