Suppose that you use the lens from your third Investigation to collect solar light at a normal incidence (Sun is 150 x 10° km away and has diameter of 1.4 x 10° km). At what distance from the lens will the image of the Sun be located? What will be the diameter of the image? What will be the irradiance (power per unit area) in the image, if the Sun's irradiance at the sea level is I 500 W/m² .
