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

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

Where should an object be placed in front of a convex lens to get a real image of the size of the object? Answer: At twice the focal length, the image formed by the convex lens is real and of the same size as the object.

At what position should an object be placed in front of a concave mirror so as to get a real and inverted image of the same size 1?

For real, inverted and reduced image, the object must be placed beyond the centre of curvature. A concave mirror produces three times magnified real image of an object placed at 10 cm in front of it.

Can a concave mirror form a virtual image of same size as the object?

A plane mirror will always produce a virtual image. A concave mirror will only produce a virtual image if the object is located in front of the focal point. A concave mirror will only produce an upright image if the object is located in front of the focal point.

Can a concave mirror form a real image?

Concave mirrors can form real images. Convex and plane mirrors always form virtual images.

What does a convex mirror do to an image?

The image produced by a convex mirror is always virtual, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point. As the object approaches the mirror the image also approaches the mirror and grows until its height equals that of the object.

What type of image does a convex mirror form?

The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. In this section, let us look at the types of images formed by a convex mirror. When an object is placed at infinity, a virtual image is formed at the focus.

What is the sign of image distance in concave mirror?

When image is formed in front of the mirror, the distance of image is taken as – (negative) and when image is formed behind the mirror, the distance of image is taken as + (positive). Height of image is taken as positive in the case of erect image and taken as negative in the case of inverted image.
