The radius of curvature of a concave mirror is 10cm. The image of the sun will be formed at a distance___ from the pole of the mirror.

Open in App

Solution

If the object is placed at infinity the image is formed at the focus.

We know the focal length is half the radius of curvature.
$F = \frac{R}{2}$ $⟹$ f = 5 cm

So the image of the sun is at 5 cm from the pole.
