Here are the equations of three waves:
(1) y(x, t) = 2 sin(4x – 2t). (2) y(x, t) = sin(3x - 4t), (3) y(x, t) = 2 sin(3x – 3t).
Rank the waves according to their (a) wave speed and (b) maximum speed perpendi-
cular to the wave's direction of travel (the transverse speed). greatest first.​

Answer 1

Here are the equations of three waves: y (x, t) = 2 sin(4x - 2t) y(x, t) = sin(3x - 4t) y(x, t) = 2 sin(3x - 3t). Rank the waves according to their maximum speed perpendicular to the wave's direction of travel (the transverse speed), greatest first. 1, 2, 3 3, 1 and 2 tie 3 and 2 tie, 1 2, 3, 1 A wave traveling along a string is described by y(x, t) = 0.00327*Sin (072.1x - 2.72t). The second wave travels along the string and it is described by y(x, t) = 0.00327*sin (72.1x - 2.72t + 3.14). For both, the numerical constants are in SI units (0.00327 m, 72.1 m, and 2.72 rad/s)
