What is focal plane of a spherical mirror?

An object is placed in front of a concave mirror. It is observed that a virtual image is formed. Draw the ray diagram to show the image formation and hence derive the mirror equation $\frac{1}{f}=\frac{1}{u}+\frac{1}{v}$.
 

An object is placed at a distance $3\mathrm{f}$ from the pole of a convex mirror of the focal length of $f$. Calculate the linear magnification of the mirror.

Define the centre of curvature of a spherical mirror?

The figure shows a ray of light falling normally on the face AB of an equilateral glass prism having a refractive index $3/2$, placed in water of refractive index $4/3$ . Will this ray suffer total internal reflection on striking the face AC? Justify your answer.

Larger aperture of objective lens in an astronomical telescope _____

A ray of light on passing through an equilateral glass prism, suffers a minimum deviation equal to the angle of the prism. The value of refractive index of the material of the prism is _____.

The path of the light is called a _____of light.
