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

Click For Summary

Homework Help Overview

The discussion revolves around the relationship between the angle of deviation and the refractive index of a prism in the context of optics.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the implications of Snell's law and trigonometric identities in understanding the angle of deviation. Some question the assumption that the angle of deviation is independent of the refractive index, while others suggest that it may increase with the refractive index under certain conditions.

Discussion Status

The discussion is active, with participants offering insights and questioning each other's assumptions. There is a mix of agreement and differing viewpoints regarding the relationship between the angle of deviation and the refractive index.

Contextual Notes

Some participants note the importance of internal reflection in the context of the problem, while others reference specific angles of incidence and emergence without providing complete information about the setup.

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.

Hi lamborg! Welcome to PF! :smile:

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.
