The magnification of the image when an object is placed at a distance x from the principle focus of a mirror of focal length f is?

A real object is placed at a distance $$f$$ from the pole of a convex mirror, in front of the convex minor. If focal length of the mirror is $$f$$, then distance of the image from the pole of the mirror is :

The refractive index of glass with respect to air is $$\dfrac{3}{2}$$ and that of water with respect to air is $$\dfrac{3}{2}$$. What is the refractive index of glass with respect to water?

You are given two lenses, a converging lens with focal length + 10 cm and a diverging lens with focal length -20 cm. Which of the following would produce a real image that is smaller than the object?

Which among these is the angle of incidence?

Magnification produced by a convex mirror is $$\dfrac{1}{3}$$, then distance of the object from mirror is

The phenomenon of bending of light at the surface of separation of two media is called :

A ray of light strikes a glass slab $$(R.l=\mu)$$ of finite thickness $$t$$. The emerging light is 

A light ray passes through a glass slab. Which of the following diagrams shows the correct path of the ray?

A plane mirror is placed along the x-axis facing negative y-axis. The mirror is fixed. A point object is moving with $$3\hat{i} \, + \, 4\hat{j}$$ in front of the plane mirror. The relative velocity of image with respect to its object is
