WebApr 6, 2024 · Derive the Prism Formula. The prism formula is derived from Snell’s law. It states the relationship between the angle of incidence and the angle of refraction. Let us understand the derivation now. μ = s i n i s i n r. (by Snell’s law) δ … WebWe know that the refraction angle must be 90 degrees to have a total internal reflection. Using Snell’s law, we get: n 1 · sin θ = n 2 · sin θ 2 1. 55 · sin θ c = 1 · sin ( 90) sin θ c = 1 1. 55 = 0. 65 ⇒ θ = 40. 2 d e g An example of refraction is a mirror.
