rays, the waves in the middle consists of infrared, visible, and ultraviolet waves. In this spectrum frequency and wavelength play a big part on which kind of wave is present. At different frequencies, (the amount of waves per second) and wavelength ,( the length of the wave measured from peak to peak) there are different waves, as these factors change so does the property of the wave. In this essay I will be talking about ultraviolet radiation. In this diagram you can see the electromagnetic

Ultraviolet radiation, also known as UV rays, is energy that comes from the sun. It falls under invisible light on the electromagnetic light spectrum. It is more towards the violet side; hence, why it is named ultraviolet light. UV rays have higher energy and shorter wavelengths. According to live science, “it has frequencies of about 8 × 1014 to 3 × 1016 cycles per second, or hertz (Hz), and wavelengths of about 380 nanometers (1.5 × 10−5 inches) to about 10 nm (4 × 10−7 inches)” (Lucas). Our eyes

The Effect of Increased Ultraviolet Radiation on Marine Ecosystems Abstract Nearly 80 percent of the Earth's surface is covered with water, nearly all of it being in the form of oceans. Therefore, any environmental changes that are sensed on a global scale are certainly expressed in aquatic ecosystems. The purpose of this paper is to explore the nature by which one aspect of the changing environment, ultraviolet radiation, affects the sensitive balance of the oceans. Specifically, the focus

The most important thing that they can do is to protect their skin from ultraviolet ray exposure and making sunscreen, with a high SPF value, a life-long habit.

the elderly people in America are infected or will develop skin cancer. What are the causes of skin cancer? The causes of skin cancer: Exposure to Ultraviolet (UV) rays, most commonly from sunlight, is the biggest cause of skin cancer (Melanoma - Causes, Symptoms, Treatment, Diagnosis - Cancer - Body & Health 2012): ULTRAVIOLET light definition and its impact on the skin (the fact). Most people who are exposed to the sun for long periods probably develop skin cancer

often preventing most tanning as well as burning, as by obstructing the penetration of ultraviolet rays. Sun block is almost a necessity for most people. Sun block is almost a necessity because certain people burn easily due to having sensitive skin. This could be very painful for certain people and it doesn’t go away easily or quickly. Two types of radiation that cause skin cancer are ultraviolet A and ultraviolet B. These two UV rays can cause sun burn, skin aging, skin damage, and skin cancer. This

Ozone Depletion A Case for “Ignoring the Facts” Ozone forms a layer of the earth’s atmosphere that protects us from the sun’s deadly ultraviolet rays. During the last decade there has been a scare set forth by environmental enthusiasts that Chlorofluorocarbons (CFCs) destroy the ozone layer. Although there has been no evidence of any CFC destruction of the ozone layer there is an international stoppage on using CFCs, as well as an executive order set forth by Clinton to limit the sell and use of

indoors or outdoors will damage the skin. And there is much more to just lying in the bed and coming out with a tan. The tanning process is a complicated process and affects more than your skin; it affects your DNA also. So if being exposed to ultraviolet light is not an option than there are many safe alternatives to having that beautiful dark skin. Bronzing powder, self-tanning creams and sprays offer a golden glow with out the harmful UV waves from indoor tanning.

affect that ultraviolet radiation has on present day society. In order to understand how the ozone affects us we must first understand what the ozone is. What is the ozone? The ozone’s essential duty is to protect society from harmful ultraviolet rays by acting as a filter. The ozone is a layer in the middle of the stratosphere that protects the earth from the harmful ultraviolet radiation emitted by the sun. The ozone layer acts as a shield and prevents the sun’s deadly ultraviolet rays from penetrating

public awareness of the risks. To first understand how you get tan or you get sunburnt you have to learn about ultraviolet radiation. Ultraviolet radiation is composed of three different wavelengths: UVA, UVB, and UVC. These different types of radiation are classified by their wavelengths, which can be measured by the depth that they penetrate your skin, and by how far they travel(Ultraviolet Radiation 1). UVA rays have the longest wavelength. They travel 360 miles to 460 miles. This type of radiation
