Energy is a system’s “ability to do work.”(Elert) The unit for energy is joules. Some other characteristics of energy are that it takes numerous forms and that it is a scalar quantity.(Elert) The two types of energy are kinetic energy and potential energy. Kinetic energy refers to an object’s motion. This differs

All electromagnetic radiation is a form of light, but human eyes can only detect visible light. Theories suggest that light is an electric field tied up with a magnetic field, flying through space. In the visible light spectrum, each color moves at its own wavelength. Light waves are similar to sound waves but light waves move much faster than sound waves. The color of an object is determined by the color light that is being reflected.

Light is a form of energy that behaves in some ways like waves. Light waves have a range of wavelengths. A wavelength is the distance between any point on one wave and the corresponding point on the next wave. Different wavelengths of light appear to us as different colors. Light that contains all wavelengths in the same proportions as sunlight appears white. See LIGHT.

Electromagnetic Radiation – A form of energy composed of waves of electric and magnetic changes (from electrically charged particles). It deals with

where  is the speed of light (). The energy ( in joules) contained in one quantum of electromagnetic radiation is described by the equation

Electromagnetic waves are continually used to upgrade and advance our technology, being implicated for its use in microwave ovens, radio waves for telecommunications and x-rays in medicine.

Quantum effects provide additional sources of EMR, such as the transition of electrons to lower energy levels in an atom and black-body radiation. The energy of an individual photon is quantized and is greater for photons of higher frequency. This relationship is given by Planck's equation E = hν, where E is the energy per photon, ν is the frequency of the photon, and h is Planck's constant. A single gamma ray photon, for example, might carry ~100,000 times the energy of a single photon of visible light.

the electromagnetic spectrum order is Radio waves, microwaves, infrared rays, visible light rays, ultraviolet rays, x rays, and gamma rays. the order is in order of wavelength, radio waves have the longest wave length and gamma rays have the shortest wave length. Each of these types of rays have different and very important purposes. Radio waves are used mostly for communications, microwaves are used to cook, radars, cellphones etc, infrared rays are used for their heat you could use them in controls thermal imaging, alarm systems and more. visible light is obviously used to see things such as printers and cds, ultraviolet rays are used to sterilize produce vitamin d etc.xrays are used to see inside people and things and lastly gamma rays are used to kill cancer cells. as helpful as all these can be they do have some harmful aspects. Large doses of radio waves are believed to cause cancer, leukaemia and other disorders, microwaves are known to cause cataracts in your eyes, infra red has a possibility of making humans overheat, with visible light Too much light can damage the retina in your eye. uv rays can cause sunburn skin cancer and damage in retna , x rays can cause cancer and cell damage and lastly gamma rays could cause cell damage and mutations. there is also a different type of ray on the electromagnetic spectrum and it has the smallest wave length its called cosmic radiation it is used in outer space and

* describe waves as a transfer of energy disturbance that may occur in one, two or three dimensions, depending on the nature of the wave and the medium

A photon of light has a wavelength of about 600 nm (1nm = 1 x 10-9 m). What is the energy of this photon of light? Show all calculations leading to an answer.

The wavelength of the wave the distance between the peak of one wave and the peak of the next, between the minimum of one and the minimum or the next, or between any two points the encompass one complete wave cycle. Equivalently, this is the distance the wave travels from when say the electron is at the peak of its motion and the next time it gets to the peak of its motion. Either way this is about 10 or so grid points.

The six different types of energy are thermal, electrical, nuclear, chemical, sound, and light. Thermal push is the part of the total electric potential energy and kinetic energy of an object or sampling of matter that results in the system temperature. Electrical vigor is the energy carried by moving electrons in an electric music director. It cannot be seen, but it is one of our most useful strains of energy because it is relatively easy to transmit and use. All topics consist of atom, and every atom contains one or more electrons, which are always moving. The energy released during nuclear fission or fusion, extrasensory perception. When

transmittance (T) represents the fraction of the original radiant energy that passes through, or is

Electromagnetic radiation are electromagnetic waves, or photons, that are emitted by astronomical bodies and travel in all frequencies (Auger, 1964). Particle radiation, on the other hand, are charged particles traveling at high speeds, protons, and even nuclei of other heavier elements. These particles tend to travel near the speed of light, so fast that their electrons are completely striped from

The strength of magnetic fields is measured in units of Teslas (T). One tesla is actually a relatively strong field - the earth's magnetic field is of the order of 0.0001 T.
