Describe the nature of image formed when the object is placed at a distance of 20 cm from a concave mirror of focal length 10 cm
Object distance (u) = - 20 m ( negative, due to sign convention)
Focal length (f) = -10 m ( negative, due to sign convention)
Image distance = ?
From the mirror formula, we know that:
Here, the negative sign means that the image is formed on the left side of the mirror. Thus, it is a real and inverted image, formed at a distance of 20 m from the mirror.
