An object is placed 15 𝑐𝑚 in front of a convex mirror, which has a radius of curvature 30 𝑐𝑚. Which one of the following is true of the image formed?

A light ray is incident on the surface of a sphere of refractive index n at an angle of incidence $\theta_0$. The ray partially refracts into the sphere with angle of refraction $\phi$ and then partly reflects from the back surface. The reflected ray then emerges out of the sphere after a partial refraction. The total angle of deviation of the emergent ray with respect to the incident ray is $a$. Match the quantities mentioned in List-I with their values in List-II and choose the correct option.
