Focal length, radius of curvature and power of a plane mirror respectively are

When an object is placed between pole and focus of a concave mirror, then the images formed are

The wavelength of a light coming from a sodium source is $645 \mathrm{nm}$. What will be its wavelength in water, if the refractive index of water is $1.33 ?$

Due to atmospheric refraction effects, the day becomes longer by

What is lateral shift with respect to optics?

An object approaches a convergent lens from the left of the lens with a uniform speed $10 \mathrm{m}/\mathrm{s}$ and stops at the focus. The image moves

A quartz prism can produce a minimum deviation $\delta$ in a light beam. Then the minimum deviation produced by three prisms combined together is

An object is seen through a simple microscope of focal length $10 \mathrm{cm}$. Find the angular magnification produced, if the image is formed at the near point of the eye which is $20 \mathrm{cm}$ away from it.
