AI Thread Summary
To calculate the reflection and transmission of candle flame images in a glass sphere, one must consider the sphere's refractive index and diameter. The candle flame, positioned 1 meter away, will create two images: one reflected off the surface and another transmitted through the glass. Ray tracing techniques can help visualize the paths of light and determine the positions and sizes of these images. Utilizing resources like HyperPhysics can provide additional guidance on ray diagrams and optical principles. Understanding these concepts is essential for solving the problem effectively.

A fortune-teller’s crystal ball is a sphere of diameter 200 mm, made of glass
with refractive index 1.70. A candle flame of height 10 mm is placed 1.00
metre away from the surface of the ball. Calculate the position and size of the
two images of the flame:
(i) reflected in the ball’s surface, and
(ii) transmitted through the ball.

I have no idea where to start on this question

We've learned nothing like this, i'd just like some help with this as it is baffling me.

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'

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...
