Lesson: Wave SuperpositionPhysics
In this lesson, we will learn how to calculate the resultant wave function of multiple wave functions occupying the same space and time as each other.
Sample Question Videos
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, 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 ?
Two sinusoidal waves are moving through a medium in the same direction, both having an amplitude of 3.00 cm, a wavelength of 5.20 m, and a period of 6.52 s, but one of the waves has a phase shift of an angle . The resultant of the waves has an amplitude of 5.00 cm. Find by using the fact that .
