a schematic diagram of the circuit would be helpful (laser part not needed in the schematic )
I think you need more explanation here, you are measuring a voltage divider as far as I can tell?
I thought you did a nice job of explaning things. Be careful with how you represent AM, you are showing an envelope, a vectorial combination in a linear system. The carrier wave does not vary in amplitude in reality, even though a scope "combines" the carrier and sidebands, suggest you make a distinction between the carrier and sidebands in your graphics (show a spectrum plot), no need to perpetuate the "misnomer" of AM. I liked when you described spheres within spheres for the EM wave, maybe some sort of attempt at a graphic of that would be nice.
The problem with EM mnemonic visualizations, none of them reflect or explains reality of EM waves. It is just a memory prop for engineering calculations. You don't have to understand chit of how a black EM box works to come up with usable engineering calculations.
Wonderfully presented!
You said resistivity but go ahead to only show for resistance
wait, what? the positive charges moved?
I noticed that too....stopped watching right there!
Fill the glass with water Place the card on top Turn the glass over, while holding onto the card and making sure the card always stays flat. Do this over the plastic tray When the glass is upside down let go of the card… 1) What is stopping the water from coming out ? 2) Why pressure inside the Glass decrease? If the reason is expansion of air then How
beautiful, easy experiment
Thanks for the helpful instructional. However, for all that fancy sensor & data logging equipment, that data set is a mess!
Could someone please tell me what data acquisition system and sensor was used for this?
Wow
quá hay
thank you William for your effort, this video was very helpful and easy to understand. best wishs.
You need make the calculations, not only to tell "is possible calculate"
but the video is too short
perfect
Thanks! This video was super clear and helpful.
I have same Ideal gas apparatus but how to connect to my laptop or smart screen
LORENZ FOOORCE GO!
Centrifugal and centripetal forces are so confusing. Shouldn't this be called centrifugal as the object tries to move away from the center? Could we simply call this inertia? Looks like the object that tends to go in a straight line is simply forced into a circular motion by the wire. I'm so ignorant ☺
Your last sentence is correct - the mass would move in a straight line due to its inertia, but the tension in the wire pulls its path into a circle. Force toward the center = centripetal. There is almost never a centrifugal force. We just think about the force pulling toward the center of the circle and think there must be something pulling outward to balance it -- but it is not balanced, that's why the mass continually moves in a curving, circular path.
@@williampeterson7749 Thank you for your explanation. This is obvious now.
Sir amazing video
That’s so cool! What antenna did you tune the dipole for? Something else you could try is having a reflector wire laid on the ground under the dipole.
Cool
Thanku
Than🙏🇮🇳🇮🇳ku
From where do you belong sir ji give more experiments videos on related topic with class 11 and 12
He is from us fool
Very useful and exciting
The maximum range is achieved around 44 degrees for light objects wherever at 37.5 degree for large objects like a javelin.
Where from you
Nice experiment
Thank you👍
Noice
Aap kaha sa hai
Mast raha expriment
Thank you
Good
hi i would like to ask the length of the string
That's a meter stick in the video which you can use for reference
Great but no likes and comments
actually there is. eeven one counts

Awesome 👍
Thanks but do you know why the right hand rule work for such a system
