What should be the position of object so as to get the image formed by a convergent lens to get virtual erect and larger than the object?

What should be the position of object so as to get the image formed by a convergent lens to get virtual erect and larger than the object?

Virtual images can also be produced by converging lenses when the object is placed inside the focal length. In that case, the virtual image will be upright and enlarged, as it will be further from the lens than the object.

At what possible positions should an object be kept in order to obtain an image so that its magnification should be greater than one?

Solution : A convex lens acts as a magnifying glass, when it forms a virtual, erect and magnified image of an object. For this, the object is to be placed between principal focus and optical cantre of the lens.

What happens when the object is placed at F?

Sample Response: The image created by the object is located on 2F behind the lens, real, inverted, and the same size as the actual object. What happens when the object is placed at F? Sample Response: No image will be formed because the rays will not converge to or diverge from a common point.

Is it possible to form a real image using a real object with a concave lens?

The concave lens will not produce real images. Real images are not formed by a concave lens since the rays passing through the concave lens diverges and will never meet.

What are the applications of convex lens in our daily life?

Uses of convex lens are in daily life are as follows : 1) Convex lens is used in microscopes and magnifying glasses to subject all the light to a specific point. 2) Convex lens is used as a camera lens in cameras as they focus light for a clean picture. 3) Convex lens is used in the correction of hypermetropia.

Why are concave mirrors used as shaving and makeup mirrors?

Concave mirrors bend inward in the center. When your face is put between a focus and the concave mirror, it will reflect a magnified image. For your face, a concave mirror can even reflect the pores and hair follicles on your skin. Concave mirrors are used as makeup mirrors or mirrors for shaving.
