Talk:Minimum deviation

D

At one point, "D" should be "D" with the subscript lambda. — Preceding unsigned comment added by 31.54.203.120 (talk) 10:26, 27 April 2017 (UTC)

Cover photo

The cover photo should be changed to this (the third pic in the article):

When the entrance and exit angles are equal, the deviation angle of a ray passing through a prism will be minimal.

The present photo is not depicting minimum deviation.

Removed part

I removed this part as it was not about minimum deviation.

The deviation angle in a prism depends upon:

1. Refractive Index($n$): The larger the refractive index, the larger the deviation angle.
2. The Angle of the Prism($A$): The larger the prism angle, the larger the deviation angle.
3. The Angle of Incidence($i$): The deviation angle first increases with increasing incidence angle and then decreases.

All these factors are quite evident from the formula in the next section.
