Light travels in waves of frequency and as particles of matter. There are many types of light, of which the visible spectrum is a small part.Know More
Visible light is the light that can be seen with the naked eye. It is one type of electromagnetic radiation, which results from the vibrations of electric and magnetic fields. Other types of light that exist in the electromagnetic spectrum include
Television, radio and microwaves also exist on the EM spectrum. These waves have some of the lowest energy levels on the spectrum while gamma rays have some of the highest. The wavelengths of these rays are not captured by the human eye and are thus considered invisible. The visual range of the EM spectrum appear in different colors.
Another way that light is said to travel is as particles, or packets of energy. These packets are called photons, which are elementary particles that carry EM force. The concept of photons was developed by Albert Einstein to describe the actions of light that did not follow the convention of waves.
Light moves very rapidly, but does have a maximum velocity of 186,282 miles per second. In astronomy, a light year equals 5.8 trillion miles, which is the distance light can travel at its maximum speed for the span of a year.Learn More
A spherical capacitor consists of two hollow, concentric spheres of oppositely charged electrodes with an insulator in between them. Physicists consider Earth to be a huge spherical capacitor surrounded by the ionosphere, with a charged atmosphere that discharges electricity to the surface of the planet in the form of lightning.Full Answer >
Atomic bombs work by splitting atoms, while hydrogen bombs, also known as nuclear bombs, draw their energy from fusing atoms together. While both types of reactions involve the nucleus of the atom, and both can therefore rightly be called "nuclear," tradition has reserved the word for the types of reactions that are exclusive to fusion devices.Full Answer >
Energy transfer is the conveyance of energy from one item to another; the transfer occurs among different scales and motions. Energy transfer may mean different things in different sciences.Full Answer >
Chlorine has exactly 17 protons. The element has an atomic number of 17, which correlates with its number of protons and electrons. Chlorine has 18 neutrons.Full Answer >
