Hello fellow students!
I’m going to discuss the
similarities and differences with sound and light. I’m going to make a list and
focus on the similarities first. After a brief statement on how the
similarities relate, I’ll make another list on the differences. After doing
some research on sound and light, and after watching the course videos, I made
up the list and tried to explain the best way I knew how in my own words. There
are possibly more similarities and differences then the ones I have written
here.
Similarities with sound and
light:
1.
Spectrums! When
perceived by humans, both sound and light use specific spectrums.
a.
Sound lives in
frequency.
b.
Light uses a
visible spectrum.
2.
Waves! Sound and
light both travel in waves.
a.
Sound and light
waves have the same physical characteristics.
b.
Sound and light
waves move in a similar way.
c.
Sound and light
can be reflected or absorbed by objects.
3.
Doppler effects!
According to Larry Rivers, “both waves exhibit the Doppler effect.”
a.
Sound and light
waves rise in frequency as they get closer and lower as they move away.
Differences with sound and
light:
1.
Light is made of
waves and particles. Sound is only made of waves.
2.
Sound produces
mechanical waves and light produces electromagnetic waves.
3.
Light waves can
travel in a vacuum and sound waves can’t.
4.
Light waves
travel faster.
5.
Light can be seen
and sound can be heard.
These similarities and
differences are put together from the research I’ve done on the subject. There is
possibly more of each that can be found, but for a basic understanding on how
light and sound relate to one another, this will work nicely.
I have always
thought about if light and sound could be captured. I would imagine that
everyone has tried or seen the trick done where you take a can and scream into
it, close it quickly, and then open it later hoping to hear a scream. I have
tried this and I have never heard a thing. I just think if it is possible then
how would it actually work. I suppose we do have a way of capturing and
controlling light and sound. If we record ourselves talking, we can play it
back and this gives us light and sound. I suppose my question should be, is it
possible to capture rouge light and sound waves from random places? While
researching light and sound waves, I learned that both can be reflected off
objects. If the light and sound waves could be tracked and certain objects
could be placed in the path, perhaps it could be possible.
