How does radius of curvature affect image size?

Increasing or decreasing the lens radius affects the size and position of the image formed by the lens. The Focal Length, Object Height, Image Position, and Image Height are presented in the space to the left of the lens, underneath the object space focal point.

What happens to the size of image when the curvature of convex mirror is decreased?

The diagram shows that as the object distance is decreased, the image distance is decreased and the image size is increased. So as an object approaches the mirror, its virtual image on the opposite side of the mirror approaches the mirror as well; and at the same time, the image is becoming larger.

What happen to the size of the image when the object become closer to the concave mirror?

The toy car image is smaller and inverted when using a concave mirror. The closer the object comes to the focal point (without passing it), the bigger the image will be.

How is radius of curvature related to focal length?

The relation between focal length (f) and radius of curvature (R) of a spherical mirror is that the focal length is equal to half of the radius of curvature i.e. f=R2.

What happens to the size of the image?

1} As object moves towards focus, image moves away from focus. 2} As object moves towards focus, image grows in size but remains inverted. 3} As object moves between focus and optical centre, image decreases in size virtually as distance from the lens decreases.

Is radius of curvature and Centre of curvature same?

Centre of curvature – It is the centre of the hollow sphere which the mirror forms a part. It is represented by C. Radius of curvature – It is the radius of the hollow sphere of which the mirror is a part.

What happens to the image size and its location as the object comes nearer the convex lens?

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 happens to the image when the object is moved away from the mirror gradually?

When the object is moved away from the mirror gradually, the size of the image reduces.

Will the image be bigger or smaller than the object?

No. Real images can be larger than the object, smaller than the object, or the same size as the object.

What is the relation between radius of curvature and focal length of a lens if the radius of curvature of a lens is 30cm find its focal length?

= 1/2 X 30 = 15cm.

What is the relation between focal length and radius of curvature of a concave mirror does the same relation holds for a convex mirror?

Answer Expert Verified Relation between the focal length and radius of curvature : For a spherical mirror of small aperture to its radius of curvature, the focal length of the mirror is one half of the radius of curvature of the mirror. This relation can be proved for both the mirrors that is concave and convex.

What happens to the size of the image of an object when it is moved gradually away from the convex mirror?

When the object is moved away from the mirror gradually, size of the mirror reduces.
