Evaluate the energy of the blackbody photons inside your eye. compare this with the visible energy inside your eye while looking at a 100-w light bulb that is 1 m away. you can assume that the light bulb is 100% efficient, although in reality it converts only a few percent of its 100 watts into visible photons. take your eye to be a hollow sphere of radius 1.5 cm at a temperature of 37◦c. the area of the eye’s pupil is about 0.1 cm2. why is it dark when you close your eyes?
