11. (a) Illustrate the " standing wave " measurement for
determining the speed of light . (b) How would we determine the
speed of light with this method?
As you observe a standing wave on a string (e.g. with a strobe
light), you notice certain times when the string is completely
flat. What has happened to the energy stored in the wave at those
instants? b) Are there any instants when the velocity of every
portion of the string is simultaneously zero? What does it look
like? Draw a picture and explain your answer.

1. Where would you expect the nodes to be? ---Select---About
half the amplitude of the incident or reflected wave.Where the wave
amplitude is highest or lowest.Where the incident wave crosses the
centerline.About double the amplitude of the incident or reflected
wave.is in phase with the incident wave.is out of phase with the
incident wave.About double the amplitude of the incident or
reflected...
I. What is the difference between a standing wave in a string
and a wave that progresses within a string?
a) in a standing wave the location of maximums and minimums
along the string is constant in time.
b) in a wave that progresses the velocity of the wave changes
with time.
c) in a standing wave the wavelength is constant, whereas in a
progressing wave it is not
d) a standing wave is only created by having an external...
Both the light and radio wave are Electromagnetic Wave. Compare
the characteristics, applications and limitations of transmissions
systems based on light wave and radio wave.
Consider the following equations for traveling waves on two different strings:(a) Which wave has the faster wave speed? What is that speed? (b) Which wave has the longer wavelength? What is that wavelength? (c) Which wave has the faster maximum speed of a point in the medium? What is that speed? (d) Which wave is moving in the positive x-direction?
Compare and contrast the photon nature of light with the wave
nature of light, making sure to address the following
properties:
a: color
b: intensity
C: energy
