Index Law Refractive index Relation

AI Thread Summary

Brewster's Law establishes a relationship between the angle of incidence (Io) and the refractive index (n) of a medium, specifically at the polarizing angle where reflected and refracted rays are perpendicular. The formula derived from this law is n = tan(Io), indicating that the refractive index is equal to the tangent of the angle of incidence. This principle is crucial in optics, particularly in understanding light behavior when transitioning between different media. The discussion highlights the importance of recognizing the conditions under which Brewster's Law applies. Understanding this relationship is essential for solving related physics problems.

Homework Statement

Using your knowledge of perpendicularity between the reflected and refracted rays at the polarising angle, find brewster's law, a relation between Io (the angle to the normal) and the refractive index n. The relation consists of no other variable or physical constant

No idea what to do here any help?

figured it out it is ok

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 '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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
