Question: Two waves have equations y(x, t) = 2 cm sin(20x - 30t) and P(x,t) = 2 cm sin(25x- 40t) where x is in centimeters

Two waves have equations y(x, t) = 2 cm sin(20x - 30t)

Two waves have equations y(x, t) = 2 cm sin(20x - 30t) and P(x,t) = 2 cm sin(25x- 40t) where x is in centimeters and t is in seconds (and the argument of the sine functions are in radians) a) Find the type, directions and speeds of both waves. b) What is the phase difference between the two waves at point x= 5 cm and t= 2s? c) At t=2s, which wave is in front of the other and by what distance. d) How many wavelengths is the trailing wave behind the lead wave at t=2s?
