thank you after 12 years

Wow

fantastic explanation, make more please

this helped me with my uni work thank you

That trick with H and T is amaizing!

4:30 that sideways 6 though, I was shocked for a moment, lmao!

Can you give an intuitive explanation for why we get a shift of 180 degrees if n1 is less than n2?

Thank you so much, other videos didn’t really have simple explanations, but my god this video blew me away! Keep it up good sir!

Good job and thank your help!

why it's 91.7 ??? 12:08 . The calculator shows 9.16.

Very underrated video! Excellent video

god bless and thank you so much you dont known how this was really anoying me just so much thaaaaaannnkkkksss😀😊😊😊😊😁

thank you this helped alot

Thank you heaps for the logical and easy to follow way you showed us how to do that :) Others have commented regarding not being able to take the root of a negative number, but that's the only thing wrong. Much appreciated, and I hope you make more videos :)

This helped thanks! =D

that helped me so much :)

I like how u explain jack shit

I don't get how u didn't add up the .35 to get the total distance between Q1 n Q3. U used .35 for all of them. Also, the formula says the charges are absolute value which means they can't be positive but u still used negative charge in ur calculations.

easy fix, just don't change anything in the third step. so you will just have v = sqrt(-(2ax)) the negatives in this case will make it possible to square root it because a negative times a negative is a positive :)

There is a problem with your math. When you were finding V. and you squared root 2ax. a was negative so you cant square root it unless we factor in i which in physics we don't.

At 8:30 minutes the image I am referring to has disappeared. This must have been an error when I compiled the video for online viewing. I think you can still follow along with what I am saying.

THANK YOU for saving me!!

I think it would be better if you wrote using a marker pen :) btw thanks for the lesson :D
