AI Thread Summary
Light is influenced by gravity, as described by general relativity, causing it to bend when near massive objects. In the scenario presented, a beam of light is directed horizontally between two mirrors positioned 7 m apart and 13 m above the ground. To find the time it takes for the light to hit the ground, calculations based on the distance and the speed of light are necessary. Additionally, the number of reflections, N, can be determined by analyzing the path of the light as it bounces between the mirrors before reaching the ground. Proper formatting and effort in problem-solving are required for homework submissions in the forum.

Falling light. According to general relativity and the equivalence principle, light is bent by gravity. Consider two tall, perfectly reflecting mirrors exactly 7 m apart and facing each other. A beam of light is directed horizontally through a hole in one of the mirrors 13 m above the ground.

(a) Determine the time it takes for the light to strike the ground.

b) The light will undergo N reflections (i.e., N/2 reflections from each mirror) before it strikes the ground. Find N.

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
