3) Only a small part of the electrical energy supplied to the tungsten lamp is transformed into visible light. Energy back the remainder turns into infrared radiation (ie heat). 15 percent of the energy supplied to a 60 W light bulb Since it turns into visible light (assume the wavelength is 490 nm), how many photons per second is the bulb publishing? (1 W=1 J/s; h=6,626X10-34 J.s) (Ctrl) -
