1What are longitudinal and transverse waves? Give one example of each.
2What are a compression and a rarefaction?
3Define crest, trough and amplitude.
4What is the relation between frequency and period? If the frequency of a wave is 50 Hz, what is its period?
5Between which points is the wavelength measured in a longitudinal wave and in a transverse wave?
6The frequency of a wave is 256 Hz and its wavelength is 1.3 m. Find its velocity.
7Sound travels through air, yet a transverse wave cannot form in air. Why?
8How are longitudinal and transverse waves produced on a slinky?
