If you add a third it will also end up to be the same. First law of thermodynamics states energy can neither be created or destroyed. Work done = Work out. Second when energy is used and powered it goes from order to disorder-entropy. Ultra violet - high frequency shorter waves, causes sunburn, infrared lower freq. long waves lower energy reds and radio
