In a compound microscope, if the objective produces an image

{I_0}

and the eye piece produces an image

{I_e}

, then

View answer and explanation

Correct option: B

{I_0}

is real but

{I_e}

is virtual

Option B (

{I_0}

is real but

{I_e}

is virtual) is correct because the objective lens forms a real image, which then acts as the object for the eyepiece, which forms a virtual, magnified image.

An object 5 cm tall is placed

\mathrm{1}\,\,\mathrm{m}

from a concave spherical mirror which has a radius of curvature of

\mathrm{20}\,\,\,\mathrm{cm}

. The size of the image is Red colour is used for danger signals because A ray of light is incident on the hypotenuse of a right-angled prism after travelling parallel to the base inside the prism. If

\mathrm{\mu }

is the refractive index of the material of the prism, the maximum value of the base angle for which light is totally reflected from the hypotenuse is Statement-A: The minimum distance between an object and its real image formed by a convex lens is

2{f}

.

Statement-B: The distance between an object and its real image is minimum when its magnification is -1. Assertion: We cannot produce a real image by plane or convex mirrors under any circumstances.
Reason: The focal length of a convex mirror is always taken negative. If both the object and image are at infinite distance from a refracting telescope its magnifying power will be equal to
