electromagnetic spectrum (EM Spectrum) is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes. The different types of EM radiation that make up the electromagnetic spectrum are microwaves‚ infrared light ‚ ultraviolet light‚ radar‚ visible light‚ radio‚ x-rays and gamma-rays. Radio: Radio waves given out by radio stations. They are also given out stars and gases in space. Microwave: Microwave radiation will cook scrambled eggs‚ but is also used by astronomers

Melanoma have main cause is exposure to ultraviolet radiation (UV) this essay is discuss of the ultraviolet radiation‚ risk factor is family history and physical and social affects. The major cause of melanoma is ultraviolet radiation (UV). The ultraviolet radiation comes of sunlight. Most occur melanoma caused by exposure to ultraviolet radiation‚ which can damage DNA. The damage DNA is become new skin cells begin to grow out of control

ROLE OF YOUTH IN OZONE LAYER PROTECTION Ozone layer plays a vital role in protecting animals‚ human beings and plants from ultraviolet radiation. Ozone layer is destroyed by a group of manufactured or human made chemicals such as chlorine bromine. These chemicals are called "ozone-depleting substances". Ozone layer is destroyed by some natural’s ways and some humane made activities. A single molecule of chlorine can break apart thousands of molecules of ozone. Chlorofluorocarbons the most widely

Science Essay: We use the electromagnetic spectrum every day it’s the microwave you use to heat your food and the cell phones you use to text! Those are part of the Electromagnetic Spectrum. The light that our eyes can see is also part of the electromagnetic spectrum. This visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow - from reds and oranges‚ through blues and purples!! The electromagnetic spectrum has 7 parts to it‚ radio waves‚ microwaves‚ infrared

When the immune cells are destroyed or damaged too in this process of cell destruction‚ the immune function of cells in that area of the skin is also destroyed which basically suppresses the immune system of the individual. Also‚ Mr immune system has a soft spot for every part of an individual’s body and the skin is not an exception; when you get sunburn from tanning or overexposure to ultraviolet radiation‚ the immune system tries

Quantum physics: The photoelectric effect What is the photoelectric effect? The photoelectric effect is when a clean metal surface emits electrons after light‚ especially ultraviolet‚ has been shone on at it. This happens because of a process called photoelectric emission whereby a single photon package of electromagnetic energy‚ called a quantum‚ is absorbed by metal surfaces. This energy is then transferred to one single electron which can then be released by the metal and that released electron

problem presently facing the world. The ozone layer protects humans‚ animals‚ and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair‚ but the problem still exists. The ozone layer is a region of the stratosphere containing ozone‚ or O3 gas. The ozone layer is necessary to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However‚ manufacturing and household chemicals that are currently in use have been found

EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for

Vitiligo Vitiligo is a skin condition‚ and sometimes is referred to as the Michael Jackson Disease. It is a skin condition in which there is a loss of pigment from areas of skin. That then results in irregular white patches of skin. Vitiligo occurs when the melanin forming cells‚ also called melanocytes fail to produce melanin. Melanin is the dark pigment that is in the epidermis that gives us our skin color. When the melanocytes fail to produce melanin‚ white patches of skin appear on the skin
