The equation of standing wave is y=0.1cos(pix)sin(200pit) . What is the frequency of the wave?

The equation of wave is y=1.0 cos 2pi(t/0.02-x/10) where t is in second. The frequency of the wave is

The equations for two sinusoidal waves propagating through a string are given by, y_(1)=4 sin (20x-30t) y_(2)=4 sin (25-x-40t) where y and x are in centimeters and t is second. (i) What is the phase difference between these two waves at the points x=5.0 cm and at t=2.0 s? (ii) When these two waves interface what is the maximum and minimum value of the intensity?

A source of wave produces 40 crests in 0.4 s. Find the frequency of wave.
