What Is the Minimum Angle of Incidence for Light to Traverse a 60-Degree Prism?

AI Thread Summary
To determine the minimum angle of incidence for light to traverse a 60-degree prism with an index of refraction of 1.6, Snell's Law is applied at both the entry and exit faces of the prism. The critical angle for the prism's exit face is calculated, which helps establish the necessary conditions for light to exit. The relationship between the angles of incidence and refraction is crucial, particularly considering the apex angle of the prism. The minimum angle of incidence is found to be approximately 41.81 degrees. Understanding these principles is essential for solving similar optics problems.

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...
