Sound & Light Travel in Waves

Jared makes a wave machine from skewers and gumdrops to demonstrate how sound and light travel.

I'm a middle school English and homeroom teacher, but your videos have been very useful to my students who are struggling with their science grades. Thank you!

Dear Sir, I have a puzzle on sound waves transformation between mic and our ear.

When we sing to the mic, it converts acoustic transverse sound waves to electrical signal. Then it goes to the Mixer, Amplifier and finally comes to the speaker. Then speaker converts it back into acoustic sound waves.

Then sound waves come to our ear and make vibratings on our ear drum. Then ear drum's nerves transform physical vibrations into a electrical signals which carry to the brain.

I wish to know that, the electrical signal which is generated by mic and our ear is same in Or different????
Mic generates elecrical signal on concept of electromagnetic induction.
But our ear generates electrical signal in different way from mic.
Do both electrical signals ( from mic and ear) are same in wave form???? And Voltage????
If you can explain briefly.

Sorry for a long question!!!!

Any issues with making one bigger and longer? Like 15 M long?

[praneethdhanushka]

Dear Sir, how do you do? I have an unclear point on Limiter ( Peak Stop). I need to know how can I adjust the Limiter in Standard way for live sound???,
Is there any rule ?? That mean the amount of volume or decible???
Thanks

Great demonstration. It really helped my first grader understand the concept of light and sound waves. Thank you

Where can I go to the (simulation) link

Your the, person who i go to when I have trouble with science

the only reason that you are here because of school

[blackwolfkills]

It will be better if u explain also about the motion of each particle in terms of forces and other things in a wave

Very nice visual sir. I came here because I have been bothered recently by video games that have poor sound design. I was considering how you would improve it, and my initial thought would be to make them work identical to each other. consider a flash light flickering in another room around the corner with the door open. The light at the corner is observed, but not as strong as if you make the corner and see the room for yourself. Now consider if music was playing in the room alongside the light. Wouldn't having them travel similarly?

[dogmomma]

What kind of sticks did you use to create this cool contraption? We would like to make something like this our kids. Do you have a separate video or a post on how to make this model? Any pointers would be appreciated.

It depends on the medium. Sound actually travels faster than light in some instances. A physics teacher in Tennessee published a paper on it.

[mazkaiventas]

Oh you're a teacher! Coodos to you sir! Good job! Keep up the amazing work!!

2 things:
one, I really want to eat the candy on the...thing
two: wow it's really satisfying when he applied energy to the wave thing

This is the first time I have been able to get into this

I tried the app and it was so cool and fun!

[worldgujarattv]

Appreciate, Mantra science in hindu culture, teaching the same thing to bring happiness in life, each mantra have different energy wavelengths, i think you can study & understand it by research.
You have demonstrated a universal Science in a simple way, Great work,
All the Best.
