Two sinusoidal waves traveling in opposite directions interfere to produce a standing wave with the following wave function, where x is in meters and t is in seconds. y = (3.00 m) sin(0.700x) cos(500t)
Determine the wavelength of the interfering waves.
m
What is the frequency of the wave?
Hz
Find the speed of the wave.
m/s
