## Where should the object be placed in front of a concave mirror to form a virtual and magnified image?

An object should be keep between focus and pole ,in the front of the concave mirror to get a virtual and magnified image of it.

## Where should an object be placed in front of a concave mirror to get a real image?

The object should be placed within the focus (between the pole and the focus) and in front of the concave mirror in order to obtain a virtual, erect and magnified image.

## At what position should an object be placed in front of a concave mirror?

The position of the object should be at centre of curvature.

## Where an object should be placed in front of a concave mirror to get a real image of the size of the object?

Answer: The object should be placed at the centre of curvature of the concave mirror to obtain an image of same size and real image.

## Where should an object be placed in front of?

An object be placed in front of a convex lens. We know that, If an object is placed in front of convex lens at twice of the focal length then the image will be real. the size of image will be same of size of object.

## Where should an object be placed in front of a convex lens in order to get 2 is an enlarged real image is enlarged virtual image?

Answer:1. anywhere between 2F and O. To form an enlarged image of an object in front of a convex lens, it should be placed anywhere between 2F and O.

## Where an object should be placed in front of a concave lens to obtain a virtual image of the object?

Object should be placed between F and 2F.

## What kind of mirror could be used and where should the object be placed to produce an enlarged real image?

Plane mirrors and convex mirrors only produce virtual images. Only a concave mirror is capable of producing a real image and this only occurs if the object is located a distance greater than a focal length from the mirror’s surface.

## Where should an object be placed in front of a concave lens in order to obtain a virtual image of the object?

A converging lens will only produce a virtual image if the object is located in front of the focal point.

## Where should object be placed in front of a concave mirror of focal length 20cm so as to obtain a two times magnified virtual image of the object?

Where should an object be placed in front of a concave mirror of focal length 20 cm so as to obtain a two time magnified real image? [2011] Ans: 30 cm.

## When object is between C and F in a concave mirror image will be at?

Properties of image:

Positions of Object and Image in Concave Mirror
Position of Object Position of Image Nature of Image
Between C and F Beyond C Real and inverted
At F At infinity Real and inverted
Between F and P Behind mirror Virtual and erect

## What is the nature of the image formed by a concave mirror if the magnification is 2?

1 Answer. (a) If m = + 4, then the image is virtual and erect. (b) If m = – 2, then the image is real and inverted.

## What is the power of a concave lens of focal length?

The distance between the pole and the principal focus is called the focal length (f) of the lens. The given focal length of the concave lens is f = -2 m. It is negative because a concave lens always has a negative focal length. The unit of power is dioptre (D) and 1D = 1m-1.
