Electromagnetic energy is a form of energy that can be reflected or emitted from objects through electrical or magnetic waves traveling through space. Electromagnetic energy comes in many examples including gamma rays, X-rays, ultraviolet radiation, visible light, microwaves, radio waves and infrared radiation.Know More
The electromagnetic spectrum is the range of all types of electromagnetic radiation (electromagnetic radiation being a type of electromagnetic energy). Electromagnetic radiation is a kind of energy that travels and spreads outward as it goes, such as the lamp sending visible light in a person's home or the radio waves coming from the radio station. People encounter electromagnetic spectrum energy all the time.
Radio electromagnetic energy can be seen not only in the radio waves captured and emitted by radio stations, but also in the radio waves emitted by gases in space and stars in space. The microwave radiation cooks popcorn and is also used by astronomers to discover the structures of nearby galaxies. Infrared energy can be seen through night vision goggles and in space it helps astronomers map the dust found between the stars. Visible light is an energy that humans can detect on their own with their naked eye. Light bulbs, stars and fireflies all emit visible light. Ultraviolet radiation is emitted by the sun and is what gives humans skin burns or tans.Learn More

Chemical energy is stored in batteries. A carbon-zinc battery contains acidic material and a rod of zinc down the center. The battery converts a chemical reaction into electrical energy.Full Answer >
According to the crafting and decorating website Primitive Crafting, the items required to make silicone-dipped bulbs are a tube of clear silicone caulk, a caulking gun, a disposable small plastic cup, a Popsicle stick, ground cinnamon, ornament hooks, 4 to 7-watt night light bulbs, disposable gloves and a string or clothesline. Ensure that the caulk is 100 percent silicone.Full Answer >
A series combination of capacitors is reduced to a single capacitor by adding the sum of the inverses of each individual capacitor, then inverting that. The equation is C_eq = (1 / ((1 / C1) + (1 / C2) + (1 / C3) + ... + (1 / C4))). When capacitors are connected in a series, the total capacitance is decreased due to the equivalent capacitor having the total plate spacing of the individual capacitors.Full Answer >
