As an example, for water waves, v w is the speed of a surface wave; for sound, v w is the speed of sound; and for visible light, v w is the speed of light. The amplitude X is completely independent of the speed of propagation v w and depends only on the amount of energy in the wave.
II A wave with a short wavelength diffracts more than a wave with a long wavelength. III The amplitude of a wave depends on its wavelength. Which of these statements is/are correct?
amplitude – maximum distance from equilibrium (from midline) wavelength – repetition distance, e.g. distance between consecutive crests/troughs. period – duration of one cycle of oscillation frequency – cycles of oscillation per unit time.
Write an equation for the wave as a function of position and time. A wave is modeled with the function y (x, t) = (0.25 m) cos (0.30 m −1 x − 0.90 s −1 t + π 3). Find the (a) amplitude, (b) wave number, (c) angular frequency, (d) wave speed, (e) initial phase shift, (f) wavelength, and (g) period of the wave.
