Two traveling sinusoidal waves are described by the wave functions where x, y1 and y2 are in meter and t is second. y1 = (5.40 m) sin[3.75πx - 1170πt] and y2 = (5.40 m)sin[3.75πx -1170πt -0.25π]
(a) Determine the amplitude of the resultant wave?
m
(b) Determine the frequency of the resultant wave?
Hz
