The equation y=25sin(120t-4x) represent a Wave motion.Determine the frequency and period

2 answers

The general equation is

y(x,t)= Amplitude*sin(2PIx/lambda +- w*t) - sign going in x direction, + sign going in -x direction.

putting your given equation in this form...
w=4
2PIf=4
f=pi/4 hz
period= 1/f= 4/PI sec
