wave is modeled with the function y(x,t)=0.25\cos(0.30x-0.90t+\frac{\pi}{3})y(x,t)=0.25cos(0.30x−0.90t+3 π ) where all lengths are in meters and all times in seconds.
- Find the wavelength of the wave.
- Find the period of the wave
- Find the wave speed (a positive number).
-What is the instantaneous velocity of one of the particles that make up the medium at position 0 at time 22 sec? Make sure to use the correct sign (plus or minus) for your answer.
