Suns rays are focused-using a lens as a burning glass

Reference no: EM13538875

The sun's rays are focused, using a lens as a "burning glass." All the visible sunlight entering a lens of radius 2.97 cm is concentrated in a circular spot of radius 1.05 mm. Find the intensity of visible light in the spot if the intensity of visible light striking the lens is 791 W/m2
