An object 7m high is placed 15cm from a convex spherical mirror of radius 45cm describe it's imagine
Thus, the image is virtual erect and behind the mirror.
Write the expression for the focal length of the mirror
Here, f is the focal length and r is the radius of curvature.
Substitute 45 cm for r in the above expression.
Write the expression for the mirror formula.
Substitute -15 cm for u and 22.5 cm for f in the above expression.
Write the expression for the height of the image.
Substitute 9 cm for v, -15 cm for u and 7 cm for h' in the above expression.
Thus, the image is 9 cm behind the mirror, it is virtual, erect and the size of image is 4.2 cm.
