Sunlight of intensity \( 1.3 \mathrm{~kW} \mathrm{~m}^{-2} \) is incident normally on a thin convex lens of focal length \( 20 \mathrm{~cm} \). Ignore the energy loss of light due to the lens and assume that the lens aperture size is much smaller than its focal
P length. The average intensity of light, in \( \mathrm{kW} \mathrm{m}^{-2} \), at a distance \( 22 \mathrm{~cm} \) from the lens on the other side is
