The ratio of the diameter of the sun to ...

The ratio of the diameter of the sun to the distance between the earth and the sun is approximately 0.009. The approximate diameter of the image of the sun formed by a concave spherical mirror of radius of curvature 0.4 m is

`4.5 xx 10^(-6) m`

`4.0 xx 10^(-6) m`

`3.6 xx 10^(-3)` m
