“Light travels faster than sound. This is why some people appear bright until you hear them speak.”

I lowkey was waiting for him to say, OK, let me shed some light on this subject
-
explained in 4 mins what my lecturer failed to explain in 40 mins
-
I have no words for the way u are presenting the topic for us. Pls keep making such videos with animations and images. Also try to make some videos related to the IIT-JEE prep, I would love it.

Omg I came here for my psycholinguistics homework two videos ago and I just can't stop watching you! I loved so much the review at the end. What a great teacher! This BA Mexican student is sooo happy!

Hi, I’m very confused. Why some say “light particle doesn’t has neutral charge”, when is supposed to be the same exact thing. If I compare transmittion of electric waves over copper vs light over (well, inside) optic fiber, I can catch that maybe because of wavelenght another conductor is needed. But there are other reactions that are different, looks like light can’t give you a shock, but electricity certainly can. Thnx in advance!

I’m very disappointed, there was so much room for a light 💡 dad joke somewhere in there haha. Awesome vid again, Thanks Prof Dave! Science is addictive, or my ocd has nothing else to focus. Either way I’m enjoying learning, bit by bit. They way it’s all sectioned out makes your page extremely easy to reference. Explain it to me like I’m 4yrs old and we are all good. Love it haha 😂

I find your videos really good to watch
-
question why isn't the b field a cos wave . Because if we see the slope of E field at points near the origin we have dE/dt maximum and Maxwell equation describes when change of electric flux is maximum magnetic field induced is maximum. I cannot find this answer if u have time plZ solve this querry.

Good stuff man. I love the quick mask cutouts!
-
u have ur own aesthetic of a science teacher thats actually cool
-
1:11 I am confused that why people represent the wave like the above one instead of the below one which is real ?
-
Best explanation 👍
-
If different wavelengths means different colours, than why colour do not change with refraction where the wavelengths change and become shorter? Thanks in advance
-
Way to go Dave! Started watching your videos even when not studying! And damn you hit me with a quiz at the end (really good idea actually!). Will support you $ when out of grad school (lol)! Can't wait for next one!
-
Reality is so weird.
-
Do we know absolutely that there is no more to the spectrum, or have we just not discovered any new way to record what may be beyond? Stupid question. I know but how can we test it or find a way to test it? Good use of Horus BTW.
-
Does the full range of the EMS measure from a Planck frequency on the low end (zero?) to an upper Planck length frequency on the gamma end? I can not find an answer to this anywhere!
-
Thank you sir this helped a lot.

Please provide me the link of how electromagnetic feild is produced
