Chapter 11: Review Questions
[Table of Contents]
11.1 Wave Motion
What is the difference between transferring energy by a wave or by giving kinetic energy to a mass?
What is the difference between a pulse and a continuous wave?
What is a sinusodial wave?
What is meant by a wavelength?
What is the amplitude of a wave?
What is the frequency of a wave?
What is the period of a wave?
How are a wave's period and frequency related?
How is the speed of a wave related to its wavelength and frequency?
How is the speed of a wave related to its amplitude?
11.2 Types of Waves
Describe a transverse wave.
Give examples of a transverse wave.
What is a longitudinal wave?
Give examples of a longitudinal wave.
What are some distinctions between longitudinal and transverse waves?
What is meant by a polarized wave?
When two wave pulses on a rope superpose or go through each other, will there always be a larger pulse formed?
How are two colliding waves different from two colliding billiard balls?
What will happen if water from two fire hoses, at right angles (90¡) to each other, run into each other?
What will happen if light from two spot lights, at right angles (90¡) to each other, run into each other?
If continuous waves from two sources interfer or superpose, can there be regions where there is no wave at all even though there would be a wave from either source if the other were not present?
11.4 Standing Waves
What are nodes and antinodes?
For standing waves on a string, are nodes or antinodes located at the ends of the string?
What is the relationship between wavelength and the length of a string when standing waves on a string are present?
What is meant by resonance?
When a string is bowed or plucked, standing waves may be caused or excited. If that string is 1.0 meters long, what are possible wavelengths for those standing waves?
11.5 More about Waves
Light and sound are both waves. Explain how we can see a ringing electric door bell inside an evacuated jar and yet not hear the bell ringing?
Why do we see distant lightning several seconds before we hear the thunder that it caused?
