Two waves are combined to form this standing wave equation of

y(x,t) = (3 mm)sin[x/(2 m]cos[(100 rad/s)t]

a. What's the amplitude of the right moving wave and left moving wave?

b. What's the wavelength of the right moving wave and left moving wave?

c. What's the velocity of the right moving wave and the left moving wave?
