A ray of light is incident on an equilateral prism made of flint...

Options

1. AThe ray suffers a minimum deviation if it is incident at angle $53^{{}^{{}^{\circ}}}$.
2. BThe minimum angle of deviation suffered by the ray is $46^{{}^{{}^{\circ}}}$.
3. CIf prism is immersed in water $\left(\mu=\frac{4}{3}\right)$ the minimum deviation produced by the prism is $14^0$.
4. DThe minimum deviation produced by the prism is $23.6^{{}^{{}^{\circ}}}$ if it is immersed in a liquid of refractive index $\mu=1.2$
