Superposition of Waves. Two important concepts that physicists study are Wave Motion Particle Motion This semester will begin with the study of wave motion. Particle motion will be studied later in the semester. the material or substance that propagates a disturbance or wave.
A crest of one wave is positioned with the crest of the other wave. The same can be said for troughs.
This represents the displacement other wave. The same can be said for troughs.
by the white wave alone.
This represents the displacement
by the orange wave alone.
Since they are both displacements
on the same side of the baseline,
they add together.
Just repeat this step for several
points along the waves.
This represents the displacement by the orange wave alone.
Since the two displacements are on opposite sides of the baseline,
the top one should be considered positive and the bottom one negative.
Just add the positive and negatives together like this.
Repeat this step for several points along the waves.
From the baseline measure to the “white” wave. Then add this to the “orange” wave. See animation.
Continuing on with this process gives
Note the white arrow would be zero in length here.
Zero white arrows added to “orange” wave occur at these other locations.
So zero added to the
“orange” wave would give
By overlaying the constructive interference curve from a previous slide you can tell that the curve of this slide is not fully constructive interference.
Interference Animation this to the “orange” wave. See animation.
In symbolic form are interfering with each other.
Remember that are interfering with each other.
How to manipulate the Hertz (Hz) unit.
Just remember that one Hz is the same as
Example: What is the speed of a wave of
frequency 500 Hz and wavelength
of 2 meters.
An example of adding waves will now be done on an overhead projector or blackboard.
