Question

size of image formed by a convex mirror is always

Answer 1

diminished

virtual and erect

Answer 2

Answer:

The size of the image formed by the convex mirror is always smaller than the size of the object.

Explanation:

• Convex lens always gives virtual image.
• The image formed by the convex lens size is one-third of the image of the object that has to be viewed.
• Convex lens is thicker at the middle and it is thinner at the edges.
• Because of this way of construction of convex lens, causes the rays of light to converge.
• That is the rays of light passes through the convex lens are brought nearer.
• Convex lens is also known as converging lens.
• When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
• It is used in the human eye. The spectacles are made of convex lens.
• Another applications of the convex lenses are magnifying lenses, eye glasses,cameras, microscopes, projector, etc.,
• Concave describes a shape that curves inwards.
• The sideview mirror of a car, which curves inwards, is a good example of a concave shape.
• Convex describes a shape that curves outwards.
