An object 5cm is placed at a distance of 20cm in front of a convex mirror of radius of curvature 30cm. Find the position, nature and size of the image.

Text Solution

Verified by Experts

Object distance,u=-20cm
object height, h=5cm
Radius of curvature, R=30cm
Radius of curvature`=2xx` Focal length
R=2f
f=15cm
According to the mirror formula,
The positive value of image height indicates that the image formed is erect. Therefore, the image formed is virtual erect,and smaller in size
