Problem with reflection and refraction.

AI Thread Summary
A 1 cm tall object is positioned 6 cm from a converging lens with a focal length of 10 cm, while a flat mirror is located 2 cm to the right of the lens. The initial calculations indicate that the image distance (di) for the lens is -15 cm, suggesting the image is on the same side as the object. The user is uncertain about the next steps, specifically whether to treat the image formed by the lens as a real object for the mirror, leading to a virtual image 17 cm behind the mirror. Clarification is sought on the correct approach to determine the final image's characteristics, including its location, nature, orientation, and size.

1. A 1 cm tall object sits 6cm to the left of a converging lens, f = 10 cm. A flat plane mirror sits 2 cm to the right of the lens. Light passes through the lens, reflects off the mirror, then back through the lens. Where is the final image? Real or Virtual? Upright or inverted? How big is it?



2. 1/f = 1/do+1/di
m = hi/ho = -di/do



3. The first thing that I did was calculate the di for the converging lens and got that to be -15 cm, which means that it will be on the same side as the object. I am kind of unsure on what to do next. Do I then take that image that was formed, make it a real object for the flat mirror, in which a virtual image forms 17cm behind the mirror? Then use 19 cm as the new object distance for my next calculation? It doesn't seem like that is the right thing to do.

I am new to forum so hopefully all this is clear.

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 hanged mass'

Thread 'A cylinder connected to a hanged 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...
