I was just wondering if anyone was aware of a good explanation or physical cause of single slit interference that doesn't involve the Huygens-Fresnel principle. To me, the principle is not very intuitive, light does not eminate from other light (as far as I know). I think I understand that the...
So I'm trying to figure out something I don't understand about the direction of radiation when a charge is accelerated. I know that when a charge is accelerated it gives off EM radiation, which I kind of picture as the electric field of the charge 'wiggling' spherically all around it. If that...
You're right I think it is option 2. So I did the problem again "assuming" a completely elastic collision with a stationary target and if energy is conserved then the MOST the golf ball can go is 69.36 m/s. So I think whoever wrote this problem meant for the final speed of the ball to be less...
Yeah I went back and used exact values before. And when I do the calculation
v=(.3*40-.046*70)/.3=29.2666 m/s=(439/15) m/s
Also, if I plug in your value of 29.666 I get 244.7 J in the end.
So I'm still stuck.
Homework Statement
In a typical tee shot, a golf ball is hit by the 300 g head of a club moving at a speed of 40 m/s. The collision with the ball happens so fast that the collision can be treated as the collision of a 300 g mass with a stationary ball—the shaft of the club and the golfer can...
Yes! Thank you so much!
I don't know what I was thinking just setting things to 1 for no reason...haha it seems so ridiculous in retrospect.
It worked out just a couple of more lines after the derivative. Thanks so much. You were really helpful and clear! :smile:
Alrighty well for the y direction I have
0=vsin(theta)t-.5*g*t^2
so v*sin(theta)=.5*g*t and that means that time in flight is t=2v*sin(theta)/g
for the x direction I have that delta x (range)=vcos(theta)*t+.5*Q*E*t^2/m where I went ahead and replaced the x acceleration with...

A particle of mass m carries an electric charge Q and is subject to the combined action of gravity and a uniform horizontal electric field of strength E. It is projected in the vertical plane parallel to the field at a positive angle \theta to the horizontal. Show that the...
Homework Statement
In a double-slit experiment, the two narrow slits are spaced 0.20 mm apart. A viewing screen is put 1.2 m behind the slits. A parallel light ray is shining on the slits.
(a) If the wavelength of the incoming light ray is 633 nm. What is the width of the central bright...
It was a first edition book, a couple of years old. I guess they packed a lot of information into that one sentence!
So I guess that means that anything with charge that is accelerating at all will act like its motion is being damped since light will carry away all of its energy and angular...
Hi I just read this in an introductory physics book "However, a spinning ball of charge would violate the laws of relativity and other physical laws." It was in a section on electron "spin".
Is that true? Couldn't I take a metal ball and put some charge on it and spin it up? Would the...
So let's say you have like a pendulum but instead of the one string you have two strings attached to two fixed supports (I tried to include a picture). Let's say you pull it back and swing it so that it is swinging in and out of the screen. Would its period of oscillation be the same as if there...
