Light Reflection and Refraction

NCERT Exercise

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.

Focal length of convex mirror, f = +15 cm
Object distance, u = −10 cm
According to the mirror formula,

v = 6 cm

The positive value of v indicates that the image is formed behind the mirror.

The positive value of magnification indicates that the image formed is virtual and erect. /p>
