A progressive wave equation is given by

y=a sin (200(pie)t -(pie)x/17)
Find;
1) The wavelength
2) Velocity
3) Frequency
4) Period

1 answer

when does 200 pi t = 2 pi ??? (when t = T :)
T = 2/200
T = 0.01 second

when does pi x/17 = 2 pi ? (when x = L)
L = 34 meters

frequency = 1/T = 100

for velocity, constant phase = constant argument
200 t = x/17
x/t = 17*200
