Photon Reflection & Transmission: Calculating Probabilities

AI Thread Summary
When a photon hits a beam-splitter, it has a 70% probability of being reflected and a 30% probability of being transmitted, as stated in the problem. To answer the question, one must recognize that these percentages directly represent the probabilities of reflection and transmission. The confusion may arise from interpreting the problem, but the values provided are straightforward. Therefore, the probability of reflection is indeed 70%, while the probability of transmission is 30%. Understanding these basic principles of photon behavior at beam-splitters is essential for solving related problems.

qw: A photon is incident on a beam-splitter. At high light intensities, the beam-splitter is known to transmit 30% of the incident light, and reflects 70% of the incident light. Calculate the probability that the photon is refected, and the probability that the photon is transmitted.
how do i answer this question? What do i need to know?

I want to say the answer is given in the problem, so I'm guessing I'm reading it wrong when I conclude the probability it's reflected is 70%
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...
