Ok, this makes more sense now. I have one more question as well. Does the quantization of light have any impact on which frequencies or wavelengths light can take on? In other words, are there an infinite amount of energies and wavelengths light can have or are there a finite number?
Ive been reading lately about the Planck constant and have been trying to learn more about it if possible.
The way I understand it, the constant came about from experiments with black body radiation. Planck noticed that the experimental data fit the equation e=hf.
My first question: how...
Thanks guys. So let me see if I understand:
If I'm moving at some velocity and another object is moving away from me, space and time will warp to make sure that I never see the object moving away as fast (or faster than) light.
If I'm a stationary observer I can see two objects moving away...
Hi, i have a question about SR. would happen if two bodies were moving away from each other at exactly .50c, and one body emitted a beam of light the opposite way it was traveling just as the other was passing? I know that simultanety is relative, but what if someone moving on the body that...
Thanks so much! =D That was a great explanation. I don't know about you guys but I think about these kinds of things ALL the time and they really bother me if I can't figure them out. That's why I love pf.
Ok, I think I understand now. the ball wants to keep pushing outward away from the centripetal force due to its inertia or centrifugal force, but it can't because of the string, so the centrifugal force is re-directed upward where it's free to move. Is this correct?
I think you're right. Each particle goes through one of two identical detectors, one where the "which path" info is erased and one where it's not. The first path still creates an interference pattern even though it still went through a detector. This proves that the detector isn't doing...
Sorry if that last post isn't clear. I meant that if you horizontally pull something (as in centripetal force) it shouldn't move the object vertically.
So how does pulling inward on a body negate the effect of gravity? In physics I learned that the horizontal and vertical components of a vector don't affect each other. Sorry if I made a mistake as I'm far from a physics expert.
Consider a ball tethered to a post by a string. The faster it spins, the higher it gets until the bAll is the same height as the place that the string is attached to the post. What force accounts for this?
Ok, this makes a little more sense now. So in the Earth's frame of view we could theoretically see the light beam receding from his craft more and more slowly as his speed increased arbitrarily close to c. But for the man in the rocket the light would always be receding at c. But if the Earth...
But if we saw his craft moving at all, even if it was moving extremely slowly due to time dilation, wouldn't that be enough to put the light's net speed over 1.0c? Sorry if I sound dumb I've only taken an introductory course in physics in high school and the instructor's explanation didn't make...
I've read that time and space dilate under acceleration to ensure the constant speed of light. I'm having trouble visualizing a scenario that illustrates this concept. Could someone please explain this to me? Thanks.
