I'm sure it's not just me, and that all of the fans of your videos on Khan Academy India and Float Head Physics are super excited to see you on the main Khan Academy channel! Thank you for making our learning journeys so much more fun and congratulations! 🥳
on an atomic level, why a moving charge produces magnetic field? and why these changing fields propagate? these are the basic physical questions you should have included too.
And as long as you have a way modulate the wave when transmitting and a protocol to define what those modulations mean so as to transcribe/decode the information
That's why the router needs to be plugged in and receive continuous electrical power to operate. This constant supply of energy allows the electrons to keep oscillating. But if it's not plugged in, the electrons will indeed stop oscillating as you describe.
All charges, including stationary ones, already have an electric field around them. But when a charge accelerates, that *changes* the electric field in the surrounding space. Kind of like the field is getting dragged around with the charge. This disturbance - the change in the E field - is what starts an EM wave.
Ref @4 minutes: Thought you had to have 2 waves to be able to talk about waves being in or out of phase with each other. How can 2 points be out of phase when they are just 2 points at different points in time within the cycle of a single wave?

Wow, you are welcome. Cheers 🎉
bro just saved my entire physics grade thank you so much. 🙏
Thank you!
Obrigado! 🇧🇷
very clear this explanation...thankyou...
Gorgeous, outstanding ❤
Sir can you make a video explaining deeply what are changing electric field and magnetic field and why do change and don't require a medium to travel
You made it easy to understand! thanks man!
Floathead physics is that you?
Yo!
Nice to see you! @Mahesh_Shenoy
Yo!@@Mahesh_Shenoy
Float Head Physics ❤❤❤
I enjoyed this video and found it very informative. Thank you for keeping my brain active during the summer Khan! Also I love this instructor 🔥
Very informative.
This instructor is amazing!
Great explanation 👌👌
These are the key points and you make so easy to understand 😊😊
Very well presented and well explained.
Mind blowing brother
Woah, perfect explanation. Have a great day!
9:41 So does that mean we separate them by their frequency?
Yes!
@ShadesOfScorn oh OK thx 🙂👍
You're awesome man thank u!

@floatheadphysics
Can't believe that's you. Lots of love as you made my understanding of physics laws sublte not malicious.
you are a genius man
Information can be transmitted through all waves as long as the receiver can detect what the transmitter is sending! 😎🤖
And as long as you have a way modulate the wave when transmitting and a protocol to define what those modulations mean so as to transcribe/decode the information

If electrons lose energy as they move as stated in 1:06, do wifi routers eventually stop working due to the electrons losing all of their energy?
That's why the router needs to be plugged in and receive continuous electrical power to operate. This constant supply of energy allows the electrons to keep oscillating. But if it's not plugged in, the electrons will indeed stop oscillating as you describe.
@@christinejackson6630 Thank you for the explanation.

Can you do euclidean geometry
Why does an electron oscillating up and down generate an electric field?
All charges, including stationary ones, already have an electric field around them. But when a charge accelerates, that *changes* the electric field in the surrounding space. Kind of like the field is getting dragged around with the charge. This disturbance - the change in the E field - is what starts an EM wave.
Nicely explained.@@christinejackson6630
If you run it in wire or transmitter and receiver even lightning you can hear on your am radio
It is Mahesh!

He keeps saying "velocity," but really means "SPEED" bc "velocity" is a vector quantity and would require a "direction" to describe it...just sayin'

Thanks for the reminder 🔥💪
@@geographynerd967 It's my pleasure
