Question

The following two traveling waves are superposed to create a standing wave: e,= (3.9 cm(sin((0.85 crn-*)x-(8.9 s-1 9,=(3.9 cm) si(0.85 cm-J&+18.9 s For each question below, enter a number and choose the appropriate units (a) What is the resulting amplitude of the standing wave? Number Select answer (b) What is the resulting wavelength of the standing wave? Number Selact answer (c) What is the resulting angular frequency of the standing wave? Number Select answer Hint O Previous Give Up & View Solution O Check Answer 0 NextExit-

Explanation / Answer

A) Resulting amplitude, A = A1 + A2 = 3.9 + 3.9 = 7.8 cm

B) wave vector, k = 0.85 cm-1

(2 pi)/ lambda = 0.85

lambda = 7.4 cm

C) Angular frequency is 8.9 s-1
