AI Thread Summary
The deviation angle in optics refers to the angle between the direction of the incoming light and the direction of the outgoing light after passing through a prism. It is calculated by measuring the angle of incidence and the angle of refraction as light enters and exits the prism. Understanding this concept is crucial for analyzing how light behaves when it interacts with different optical materials. Visual aids, such as diagrams of prisms, can significantly enhance comprehension of deviation angles. Overall, grasping the deviation angle is essential for studying optics effectively.

Homework Statement


I don't quite understand what deviation or the deviation angle is.


Homework Equations

The Attempt at a Solution


I have no idea what it is. Is it the angle that it enters the prism - the angle that it leaves the prism.

I used the Search menu at the top right of the thread to do a custom Google search of the PF for Optics Deviation Angle. There were lots of hits, but this one has a very nice prism figure that should help:

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
