Angle of deviation and angle of incidence?

Click For Summary
SUMMARY

The discussion focuses on calculating the angle of deviation for red light passing through a prism with an apex angle of 59.6° and an angle of incidence of 54.8°. The index of refraction for red light in silica flint glass is 1.62. The equation used for the calculations is n1θ1 = n2θ2, which relates the angles of incidence and refraction based on their respective indices of refraction. The participants confirmed the correct application of the apex angle in the calculations.

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
