The angle of incidence for a ray of light at a refracting surface of a prism is \(45^\circ\). The angle of 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. \(45^\circ;\ \frac{1}{\sqrt{2}}\)
2. \(30^\circ;\ \sqrt{2}\)
3. \(45^\circ;\ \sqrt{2}\)
4. \(30^\circ;\ \frac{1}{\sqrt{2}}\)
