Light, incident on the face AB, of an equilateral prism (made from a material of refractive index μ ), undergoes total internal reflection at the base BC and then falls on the other face AC of the prism. The angle of emergence, from the face AC, would equal
(1) \(sin^{-1}\left[μsin(\frac{\pi}{3}-sin^{-1}(\frac{1}{μ}))\right]\)
(2) \(sin^{-1}\left[μsin(\frac{\pi}{3}+sin^{-1}(\frac{1}{μ}))\right]\)
(3) \(sin^{-1}\left[sin(\frac{\pi}{3}+sin^{-1}(\frac{1}{μ}))\right]\)
(4) \(sin^{-1}\left[sin(\frac{\pi}{3}-sin^{-1}(\frac{1}{μ}))\right]\)
