Question B4
Two waves in a ripple tank meet at a point. One wave has an amplitude of 5.0 mm, the other wave has an amplitude of 3.0 mm.
a) i. Give the maximum possible amplitude of the wave at the point. [1]
ii. Give the minimum possible amplitude of the wave at the point. [1]
iii. Give the name of the process by which the waves are added. [1]
Two coherent sources of waves (X and Y) are arranged 15.0 cm apart in a ripple tank, and the resulting fringe pattern is observed.
