Angle of deviation and angle of incidence?

Click For Summary

Homework Help Overview

The discussion revolves around a two-part physics problem concerning the angle of deviation and angular dispersion of light passing through a prism, specifically focusing on the refractive indices of violet and red light in silica flint glass.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the application of the refractive index and the apex angle in calculating the angle of deviation and angular dispersion. There are questions regarding the correctness of the initial assumptions made about the angles used in the calculations.

Discussion Status

Some participants have offered feedback on the original poster's approach, suggesting a potential misunderstanding regarding the use of the apex angle. The original poster has indicated progress in their understanding, but there is no explicit consensus on the correctness of the initial solution.

Contextual Notes

The problem includes specific values for the refractive indices of different colors of light and requires calculations based on these values, but the original poster has expressed uncertainty about their work and has requested clarification.

What is the angle of deviation for the red ray passing through a prism of apex angle 59.6◦ if the angle of incidence is 54.8◦? Answer in units of◦.

12) What is the angular dispersion of visible light with the same angle of incidence? Answer in units of◦.

Homework Equations

Anybody?!
 
*BUMP* Anybody?!
 
I think you've used the apex angle for the initial angle of incidence of the red ray.
 
I figured it out ^thanks
