Chapter 16, Problem 92P

To determine

To find:

a) Plot resultant wave as a function of t for $x = 0,\frac{\lambda }{8},\frac{\lambda }{4},\frac{3\lambda }{8},\frac{\lambda }{2}.$

b) The direction of the travelling wave.

c) How can you change the original wave to the resultant wave?

d) The place at which the oscillation amplitude is maximum.

e) The place at which the oscillation amplitude is minimum.

f) How is the maximum amplitude related to the amplitudes of the original two waves?

g) How is the minimum amplitude to the amplitudes of the original two waves?
