Can a virtual image by photograph by a camera ?

How is the virtual image formed (photo-graphed) by a camera ?

What is a virtual image ?

By which method you get a virtual image by using a concave mirror ?

How do you get a virtual image using a concave mirror ?

How do you get a virtual image using a concave mirror?

If focal length of the concave mirror is 20 cm, we get virtual image if the object placed at a distance……..than 20 cm

a) The angle subtended at the eye by an object is equal to the angle subtended at the eye by the virtual image produced by a magnifying glass. In what sense then does a magnifying glass provide angular magnification ?

Use the mirror equation to deduce that : c) the virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole. [Note : The exercise helps you deduce algebraically properties of images that one obtains from explicit ray diagrams.]

At where the object is placed to get a virtual image in front of concave mirror.
