An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position and nature of the image.

We can find the position of image by calculating the image distance, v.

Here, Object distance, u =- 10 cm (To the left of mirror)

Image distance, v = ? (To be calculated)

And, Focal length, f = +15 cm (It is a convex mirror)

Putting these values in the mirror formula:

We get:

So, Image distance, v = + 6cm

Thus, the position of image is at a distance of 6 cm from the convex mirror on its right side (behind the mirror). Since the image is formed behind the convex mirror, therefore, the nature of image is virtual and erect.
