The wave function for a traveling wave on a taut string is (in SI
units)
y(x,t) = 0.375 sin (14pt - 2px + p/4)
(a) What are the speed and direction of travel of the wave?
speed _____ m/s
direction_________
(positive x-direction, positive y-direction, positive z-direction,
negative x-direction, negative y-direction, negative
z-direction)
(b) What is the vertical position of an element of the string at t
= 0, x = 0.178 m?
________m
(c) What is the wavelength of the...
