In prism, is angle of deviation related with the refractive index of prism?

AI Thread Summary
The discussion centers on the relationship between the angle of deviation in a prism and its refractive index. Participants note that for specific angles of incidence, emergence, and deviation, the angle of deviation may increase with a higher refractive index. Snell's law and trigonometric identities are suggested as tools for further explanation. One user highlights a misunderstanding regarding internal reflection in the context of the angle of incidence equaling the angle of the prism. Ultimately, the conversation emphasizes that the angle of deviation is influenced by the refractive index under certain conditions.

Optics, prism and angle of deviation

1. Angle of incidence, emergence and deviation are respectively 30, 60 and 45 degree.

3. I think that it is irrespective of the refractive index.

Why?

Explain, using Snell's law (the sin/sin law), and basic trigonometric identities :wink:

Oh yeah, I just forgot about that. Need to revise. :)


Thanks
 
Also, your image does not show any internal reflection to begin with. So I don't understand your qualification:

"... such that no internal reflection takes place ..."
 
In case the angle of incidence is equal to the angle of prism ,the angle of deviation increases with increase in refractive index. THUS angle of deviation increases with increase in refractive index.
 

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 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...

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...
