Two sinusoidal waves are moving through a medium in the positive -direction, both having an amplitude of 7.00 cm, a wave number of 3.00 m−1, an angular frequency of 2.50 s−1, and a period of 6.00 s, but one has a phase shift of an angle rad. What is the displacement of the resultant of these waves at a time and a position ?
Two sine waves travel along a string, modeled as and , where is measured in meters and is measured in seconds. What is the height of the resultant wave formed by the interference of the two waves at the position at the time ?
What is the displacement of the resulting superposition of the three wave functions sin , sin , and sin at the position at the time ? For each of the wave functions, is measured in meters and is measured in seconds.
