Question

An object is placed at 4 cm distance in front of a concave mirror of radius of curvature 24 cm. Find the position of image. Is the image magnified ?

Open in App
Solution

Here, R = 24 cm

So, f = R/2 = -12 cm (Negative as it is a concave mirror)

u = -4 cm

As the object is placed at 4 cm, this means it is present between pole and focus.

Now, 1v+1u=1f1v+14=112v=6 cm

Magnification, m=vu=64=1.5

As m > 1, the image is magnified.
