A wave is described by y = 0.020 2 sin(kx - ωt), where k = 2.22 rad/m, ω = 3.64 rad/s, x and y are in meters, and t is in seconds. (a) Determine the amplitude of the wave. m (b) Determine the wavelength of the wave. m (c) Determine the frequency of the wave. At a given point in space (x = 0 for example), the period is the time between the arrival of identical points on the wave. For a sin function, this occurs when the argument increases by 2π. Hz (d) Determine the speed of the wave. m/s

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
