Wave function is expressed as:
Speed of a wave is:
v = ω/k = 14π/2π = 7 m/s and is in positive x-direction.
The speed and direction of travel of the wave is 7 m/s in the positive x-direction.
The wave function for a traveling wave on a taut string is (in SI units)
y(x,t) = 0.375 sin (14πt - 2πx + π/4)
(a) What are the speed and direction of travel of the wave?
speed _____ m/s
(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?
(c) What is the wavelength of the wave?
(d) What is the frequency of the wave?
(e) What is the maximum transverse speed of an element of the string?
