Color of central circle in Newton's rings

AI Thread Summary
The color of the central circle in Newton's rings differs between transmission and reflection cases due to variations in light intensity. In transmission, more light reaches the observer, resulting in a bright central circle, while in reflection, less light is present, leading to a dark circle. The discussion emphasizes understanding the conditions under which phase reversals occur, which affect the appearance of the rings. Clarifying the thought process behind the observation is crucial for providing a comprehensive explanation. Overall, the differences in light behavior in these cases are fundamental to understanding the phenomenon of Newton's rings.

Hello guys ,
Can someone explain me why color of central circle in transmission case is bright whereas it is dark for the reflection case?
Thanks a lot,

Because you get a lot of light coming from there in one case and not the other.
 
Do you understand why rings are produced?

Have a look at the circumstances when sharp phase reversals do or don't take place.
 
@justawebuser: in order to best answer your question, we need to know how you are thinking about Newton's rings in the first place.
It is not obvious how the issue is a problem for you.
i.e.
why would you expect matters to be otherwise?
how do you think the rings are made in the first place?

Without some idea of how you think, we are unlikely to be able to help you.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

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...

Thread 'Newton's first law?'

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?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

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...
