[" 3.Magnification of a body of size "1m" is "],[2" ,what is the size of the image "]

If the magnification of a body of size 1 m is 2, what is the size of the image ?

An object 1.5 cm in size is placed on the side of the convex lens in the arrangement (a) above. The distance between the object and the convex lens is 40 cm. Determine the magnification produced by the two-lens system, and the size of the image.

Does size of mirror affect the nature of the image ?

The magnification of the image formed by the spherical mirror is m= -1.25. Based on this information, answer the following questions.If the size of object is 2 cm, then what is size of the Image ?

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?

Assertion : The focal length of the mirrorr is f and distance of the object from the focus is u , the magnification of the mirror is f//u . Reason : Magnification =("Size of the image")/("Size of object" )

At what distance in front of a concave mirror (f = 10m) an object is to be placed so that the size of the image will be halved of the size of the object?
