Geometrical Optics: Construct Ray Paths for Lens-Mirror System

AI Thread Summary
The discussion revolves around constructing ray paths for a system involving a convex lens and a convex mirror. Participants express frustration over the poorly worded question, noting the lack of crucial details like the radius or focal length of the mirror and the lens's position relative to the mirror's focal length. Suggestions include drawing the lens and mirror, marking focal points, and using a parallel ray to trace the path. The approach involves trial and error, starting with the outgoing ray and then drawing a symmetrical incoming ray. The conversation emphasizes the need for clarity in optical problems to facilitate understanding.

A convex lens of focal length f is placed in front of a convex mirror having the same principal axis as the lens. Construct the path of a ray of light which coincides with the corresponding ray emerging from the lens-mirror system, and the path of the ray whose corresponding emergent ray is its symmetrical with respect to the principal axis.

Does this make any sense to anyone?

I believe this is the worst-worded ray-diagram question I have eaver read. Do they mention what the radius or focal length of the mirror is? Is the lens placed inside or outside the mirrors focal length?
 
Absolutely nothing! Most questions involved in this course I am taking are similar to this, & most of the times I'm not quite sure where to start.

I think it's trial & error all the way ...

Well then, draw a lens and a mirror. Put in the focal points. Start with a parallel ray and see where it goes. Take the outcoming ray and draw a new ingoing ray that is symmetrical to the first outgoing ray.

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...
