Question

magnification of the image formed by a spherical mirror is +2.identify the type of mirror in the image

Answer 1

The correct answer is - The image is greater in size than the object and in an upright position.

Spherical mirrors are mirrors which have curved surfaces that are usually painted on either of its one sides. Spherical mirrors which have painted inward surfaces are called as convex mirrors or diverging mirrors, whereas, while the spherical mirrors which have painted outward surfaces are called as concave mirrors or diverging mirrors.

The mirror usually has a magnifying or a reducing effect on the image, which is slightly different from the real size of the object.

The magnification, 'm' value is usually defined as the ratio of the height of the image to the height of the object. This ratio value is related closely to the ratio value of the distance of the image to the distance of the object.

When the magnification is 1 (+ or -), it means that the size of the image is same as that of the object, and if m is greater than 1, then the size of the image is larger than the size of the object, and if m is less, then the image size is smaller than the size of the object.

If the 'm' value is a positive value, then the image is corresponding to the position of the object and if the 'm' value is negative, then the image is inverted when compared to that position of the object.
