Beat Frequency

[sinvanderwood]

I’m always telling people this is the best channel on YouTube to really understand physics concepts without having to go to school for it.

The visuals and the script always come together for a really edifying experience. One of my favorite YT channels, and one of the oldest in the biz. Thanks!

I knew beat frequencies. But today, I understood why we subtract to get beat

[InfiniteCyclus]

I love how you visualize difficult concepts to make them understandable...

[jacobohnstad]

I have nothing but praise for this channel. Direct to the point concepts that are not over explained yet also shows you the concept from every angle.

A video of yours where I actually felt like I already knew what was happening lol.
Extra bit for my music friends: this is exactly how a flanger works. It doubles the track and slows one down very slightly, leaving a very cool whirling kind of sound.

Very Cool Creative Physics Video!!! Thanks for Sharing!!! 👍😎

How cleverly explained: Waves start at the same time. Thanks bro.
You taught me how to think. Good Stuff. Never stop exploring.

Love it! Should do a video on Local Gauge Symmetry and forces next.

I used to tune my guitar using beat frequencies before tuning devices/apps. I didn't like tuning forks and they weren't cheap, then, either. For example: on the E6 string if you play the A note (on the 5th fret) and the open A5 string below it, when the two notes played together are close, you can hear the beats. The closer to each other, the fewer beats and the longer they get. When they get further apart the beats get shorter and faster. The only caveat is you have to establish standard (A440/432 -- take your pick) and then tune everything to it. Musicians know this but for non musicians: FYI.

This explanation is gold just like this channel. These 2 innocent arrows labeled imaginery and real finally helped me understand why complex numbers are part of the fourier equation. I've watched so many animations and fiddled with plenty of tools that attempt to explain fourier and they all miss the point of explaining the why when it comes to complex numbers. This video explained the why without even attempting or even uttering the word complex. 👏🏼

This is not a channel, but a real treasure💐❤️

[Cassandra_Johnson]

Good visualization for a seemingly simple idea that is really complicated.

[azhankhan]

Outstanding video, my concepts of beat are now thoroughly clear. Thanks

[pantherplatform]

I can watch this channel on repeat nonstop

[TopRPDRvideos]

This is how I used to tune the strings of my guitar to each others when I didn't have a tone meter at hand. Very handy

[quantumboy]

To be honest I have only read about the beat frequency in a mug up way or never try to contemplate over it in a rigorous manner. But your video has utterly makeover the whole scenario regarding this topic and propel me to cerebrate over this tantalising topic with a utter new perception. 😀😀😀😀

Thank you! I'm a high school student. I didn't actually comprehend how beat frequency occurs tho I passed the chapter of Waves and optics just by using the formulae prescribed in the textbook syllabus of government.

[axoid]

Thanks for the informative video. This is something I've come across several times with music but never understood what caused it.

[jkinkamo]

Thanks for this cool lecture! I wish I knew this channel in 1981 when I studied beat frequency osc's & detectors.
