Today we look at some sound wave physics! #sound #physics #science #soundscience #stem #steam

Interesting how the note the ball makes when hitting the tuning fork is an octave and a 5th above it. One of the harmonics, not the fundamental

I was playing my bass one day and discovered that the glasses in my cabinet are tuned to "G"

[yououtuber]

That is why I keep friends who resonate with me

[arthurluwuge]

Resonance is one of my favourite concepts. Such a powerful force

[vampirongosangronzon]

Frequencies are incredible. If you play a guitar or bass very loud inside a house there is always a chord that move the whole house. My apartment is in A.

[matthewnorman]

It is the same way 2-way radios know when to receive audio and play the sound from the carrier wave.

[MultiCren]

You can do this on stringed instruments too. If you match the pitch of another string it will spontaneously vibrate.

[liveintermission]

My dude just explained the calibrated skulk sensors

[hieronymusbutts]

It's called sympathetic resonance. A lot of classical Indian music relies on unplucked strings that are only activated by sympathetic resonance, which is part of what gives it a droning sound.

[teinspringz]

This is true about life, find the people with the same frequency as you so it bounces your ping-pong ball

Great trainer and science teacher. 👏 We need trainers like this throughout the world.

[mikeag]

This is fundamentally how radio communication works. Two resonators matched the same frequency and you vary how strong (AM) or how exact (FM) the transmitter frequency is to the receivers frequency.

People who can make learning fun are truly talented people

[hitts]

Bro almost dropped the tokyo drift beat 😂😂

[ryonatimefun]

I love science demonstrations like this

[kevinlalla]

Why I didn’t have a physics teacher like this in secondary school. Such a great way to explain resonance.

[malcolm]

My cats tripped the heck out to this video lolll

[larcomj]

Great example. I think this is a good way to show how resonant inductive wireless power transfer works. Amazing how seeing the effect makes such an impact.

[HighMojo]

I like how you used a ball to visibly illustrate the sympathetic vibration.

[matthewnorman]

Old 2-way radios (walkie talkies)worked by using grown crystals cut at the right size for the proper frequency resonance to activate the receiver. Every radio had a slice of crystal in it. Pretty wild.
