1)The resultant wave from the interference of two identical waves traveling in opposite directions is described by the wave function y(x, t) = (2.49 m)sin(0.0458x)cos(5.40t), where

x and y are in meters and t is in seconds. a) What is the frequency of the two interfering waves? What is the wavelength of the two interfering waves? (c) What is the speed of the two interfering waves?
