Indicate true or false in each of the following
statements:
A standing wave is the superposition of two waves
The beating of two waves can be heard as a much higher frequency
than the sum of the two frequencies.
The second harmonic is twice times the frequency of the
fundamental.
Constructive interference occurs when the phase difference of two
otherwise identical waves is 2π or multiples thereof.
A node is a position on a standing wave of maximum displacement
Homework Answers

Evaluate each of the following as true or false? true false White light is monochromatic. true false The reflected component of light traveling from one medium into another of lower refractive index will under go a phase change of 180 degrees relative to the incoming light. true false Constructive interference occurs when two waves differ in phase by 180 degrees. true false A phase difference of 360 degrees is the same as a path difference of one wavelength. true false Monochromatic light has one frequency.

12. A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingers. This is often done as a physics demonstration, creating a high-pitched, very annoying whine. From a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tube. In particular, both ends of the rod are anti-nodes. What is the fundamental frequency of a 2.50 m -long aluminum rod? The speed of sound in...
