1.Your television produces light energy by transforming electrical energy into light energy. Light energy comes from the vibration of electrically charged particles.
2.In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).
