A Concave Mirror Of The Radius Of Curvature R

A Convex Mirror Of Radius Of Curvature R

The sun subtends an angle (1^(@))/(2) at the pole of a concave mirror. If the radius of curvature of the mirror is 15 m , what will be the size of the sun's image formed by the mirror?

A concave mirror of radius of curvature R has a circular outline of radius r. A circular disc is to be placed normal to the axis at the focus so that it collects all the light that is reflected from the mirror from a beam parallel to the axis. For r gt gt R , the area of this disc has to be at least

A double convex lens ( R_(1)=R_(2)=10 cm ) having focal length equal to the focal length of a concave mirror. The radius of curvature of the concave mirror

A concave mirror has radius of curvature r and focal length f . The condition under which a diminished inverted image will be formed is

A concave mirror has radius of curvature r and focal length f. An object is placed at a distance u from the mirror. The condition under which an inverted image of the same size of the object will be formed is
