Ultraviolet

Did you know that most of the ultraviolet light produced by the Sun is blocked by the atmosphere, but some light does still reach Earth? Ultra violet light can be detected using electronic devices. Important terms that will be discussed in this paper are ultraviolet light, photochromism, chemical reactions, and absolute zero. Relating to electromagnetic radiation having wavelengths shorter than those of visible light but longer than those of x-rays. Ultraviolet radiation is emitted by the sun…

The most common cause for skin cancer is sun exposure. The sun contains ultraviolet (uv) rays, an invisible kind of radiation that can penetrate and change skin cells which eventually leads to skin cancer. Ultraviolet radiation hampers the body’s ability to fight off cancer, depleting the energy that skin cells need to repair damaged DNA and profoundly suppressing the skin’s immune system. A…

such as Ultraviolet, Infrared, fluorescent, and LED lights, and they all can do different things. Ultraviolet light can be used as a way to light up certain types of clothing, or it can be used to sterilize food. Infrared light is mainly used as a way to heat up food, or as a shorter wavelength to control household items, such as televisions and DVD players. Fluorescent light is created by an electric current running through types of stable gas, which in turn produces short wave ultraviolet…

The sun radiates energy in a wide range wavelength. Ultraviolet rays reach the earth surface in wavelengths that range between 290 and 400 nm. The impact of the wavelength to the surface of the earth is determined by size of the wavelength. When the wavelength is short, it causes a more energetic radiation that in turn creates more harm to the surface. Ultraviolet light is a form of electromagnetic radiation that is invisible to the human eye. The sun is a source of radiation that forms the full…

the sun, this is hours that the sun has the most radiant and the rays hit you the most. Another prevention that you can use is to not be a user of the tanning beds since it can burn your skin and the light in the tanning bed that tans you is an ultraviolet light that is harmful for your skin.…

Actinic Keratosis (AK) is a skin disease in which lesions form on the skin due to being over-exposed to ultraviolet light rays. This disease may develop into Squamous Cell Carcinoma (SCC). AK is usually pretty common lesions on the skin that are usually red, brown, or nude colored, rough patches on the skin that has been over-exposed to UV light rays. The more of AK that a person has, the more of a risk the person has of developing melanoma skin cancer. As AK grows and develops, it can become…

form of cancer and it accounts for at least half of all cancers .In fact, It is especially common among people with light skin .Also, It occurs when unrepaired DNA damage to skin cells which is the largest organ in our bodies. most often caused by ultraviolet radiation from sunshine and tanning beds triggers mutations, or genetic defects, that lead the skin cells to multiply rapidly and form malignant tumors. Within the past three decades, more people were diagnosed with skin cancer than all…

Then, using the same procedure as before, the solutions ' ultraviolet absorptions at 450 and 595 were determined and recorded in Table 4. As for the BCA assay, 100 microliters of each ovalbumin dilution were combined with 900 microliters of BCA, and the resulting solution were analyzed with a spectrophotometer in…

beneficial. Sunlight is needed for Vitamin D and energy, but the sun also produces Ultraviolet-A (UVA) and Ultraviolet-B (UVB) rays that can harm the body. Even though the sun’s rays can do damage to the body, many Americans choose to tan. According to skincancer.org, nearly 30 million Americans choose to tan indoors with the use of tanning beds. Like the sun, tanning beds also produce harmful UV-A and UV-B rays. Ultraviolet (UV) radiation from tanning beds can have many negative effects on the…

Basal Cell Carcinoma is a type of skin cancer. The main cause of the illness is ultraviolet light, which is found in sunlight, tanning beds, and tanning lamps. A spot infected with Basal Cell Carcinoma could have several different appearances. One example is a flat, pale yellow area that is very similar to scar. Another appearance is a reddish, itchy patch, that may appear to just look like a rash. Others might look like pink or red bumps with darker areas in them, or open sores that won’t heal…
