The angle of incidence for a ray of light at a refracting surface of a prism is \(45^{\circ}\). The angle of the prism is \(60^{\circ}\). If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are:

1. \(45^{0},~\sqrt{2}\) 2. \(30^{0},~\sqrt{2}\)
3. \(30^{0},~\frac{1}{\sqrt{2}}\) 4. \(45^{0},~\frac{1}{\sqrt{2}}\)
