Track and visualize how energy flows and changes through your system. Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy. See how energy is transferred between objects.
Electrical energy can, in turn, produce thermal energy and light, such as in an electric heater or a light bulb. Light is just one kind of electromagnetic radiation, or radiant energy , which also includes radio, infrared, ultraviolet, X-rays, and gamma rays.
28 sie 2023 · A light source or source of light is a physical object or device that emits visible light, illuminating its surroundings. As a result, while sunlight is the dominant source of light on Earth, other sources of light do exist such as incandescent, luminescent and gas discharge sources.

When a light wave with a single frequency strikes an object, a number of things could happen. The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object.
Heat is a type of energy transfer that is caused by a temperature difference, and it can change the temperature of an object. As we learned earlier in this chapter, heat transfer is the movement of energy from one place or material to another as a result of a difference in temperature.
