The displacement of a particle in a medium due to a wave travelling in the x-direction through the medium is given by y = Asin(αt = βx), where t = time, and α and β are constants.
(a) The frequency of the wave is α.
(b) The frequency of the wave is α/(2π).
(c) The wavelength is (2π)/β.
(d) The velocity of the wave is α/β.
