How to find angle between two inclined plane mirrors?

AI Thread Summary
To find the angle between two inclined plane mirrors, one can use the formula for the angle of deviation, which is given by 360 - 2#. When a ray of light is incident on the first mirror and is parallel to the second, the angle of deviation can be calculated as 180 + #. In this case, if the angle of inclination is 60 degrees, the angle of deviation would be 240 degrees. Thus, the angle between the two mirrors can be determined using these relationships.

Two plane mirrors are inclined to each other at an angle. If a ray of light incident on the first mirror is parallel to second mirror, is reflected from the second mirror parallel to the first mirror then what is the angle between the two mirrors.
please help me solve it.

ya i did but it isn't helping
tried it many a times

Use the formula:- angle of deviation between initial ray and final ray=(360-2#) where # is the angle of inclination between two mirrors. First find out angle of deviation then put the value in the formula.

Here angle of deviation is (180+#) and angle of inclination is 60.

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...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
