Re: [Phys-l] Snell's law, critical angle and Huygen's construction



How far can you trust a source that repeatedly defines the angle of minimum deviation in a prism, in this way?

"Prisms are typically characterized by their angle of minimum deviation d. This minimum deviation is achieved by adjusting the incident angle until the ray passes through theprism parallel to the bottom of the prism"

p.s. when N< 1 is substituted in the formula for prism min. deviation, the deviation is negative, as expected. BTW, I couldn't solve the eq.** for the deviation, and didn't find by googling -- anyone know?
