Sunlight of intensity 1.3 kWm2 is incident normally on a thin convex lens of focal length 20 cm. Ignore the energy loss of light due to the lens and assume that the lens aperture size is much smaller than its focal length. The average intensity of light, in kW m2, at a distance 22 cm from the lens on the other side is Sunlight of intensity 1.3 kWm2 is incident normally on a thin convex lens of focal length 20 cm.
