WebOct 20, 2024 · The rays from sun coming from infinity are parallel to principal axis after reflection they converge at a point, known as focus. Therefore, focal length (F) of concave mirror is 15 cm. And we know that same size, real and inverted image is formed by concave mirror when object is placed at centre of curvature = 2×Focal length (F).

WebAnswer. Sun is at infinite distance from the surface of the earth. Now light rays from sun rays after reflection from concave mirror will converge at focus. It is given that sun rays converge at 15 cm. So, focal length of the mirror = f = 15 cm. In case of a concave mirror, the size of image and object will be same if the object is placed at 2f.
