Are photons effected by traveling through electric or gravitational potential differences? If so, how so?
Do Photons Experience Changes in Potential Fields?
AI Thread Summary
Photons are not affected by electric fields due to their lack of charge, but they do respond to gravitational potential differences, which can lead to energy changes manifested as redshift or blueshift. The discussion raises questions about the interaction of the electric and magnetic components of electromagnetic waves with electric fields. Additionally, there is a request for the mathematical explanation of how gravitational effects cause these shifts in light. Overall, the conversation explores the dual nature of photons in relation to gravitational fields while clarifying their behavior in electric fields. Understanding these interactions is crucial for deeper insights into the behavior of light in varying potential fields.
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Hello!
I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below.
Here is how I wrote the condition of equilibrium forces:
$$
\begin{cases}
F_{g\parallel}=F_{t1}+F_{t2}, \\
F_{g\perp}=F_{r1}+F_{r2}
\end{cases}.
$$
On the other hand...
