A real, inverted and equal in size image is formed by

A converging lens forms a real image $I$ on its optic axis. A rectangular glass slab of refractive index $\mu$ and thickness $t$ is introduced between the lens and the image $I$. The image $I$ will move

The distance between a convex lens and a plane mirror is $10 \mathrm{cm}$. The parallel rays incident on the convex lens, after reflection from the mirror, form image at the optical centre of the lens. Then the focal length of the lens is

The deviation angle produced by a thin glass prism when it is immersed in water is

[Angle of prism $=4{°}_{\alpha ,}{\mu }_g=1.5, {}_{\alpha }\mu _w=\frac{4}{3}$]

If the refracting angle of a prism is $60°$ and minimum deviation is $30°$, then the angle of incidence will be

In a compound microscope, the intermediate image is

The magnifying power of a simple microscope is (when final image is formed at $D=25\mathrm{cm}$ from eye)

The image formed by the objective of a compound microscope is
