What are UltraViolet Waves?
The UV rays
It shows how close the UV rays are to the Ozone Layer
Most hospitals use this type of UV light. But its mostly use on insects
It shows where Ultraviolet light is on the Spectrum
UV-A (near the UV light): 315-400 nm.
UV- B (middle of the UV light): 280-315 nm.
UV- C (far from the UV light): 180-280 nm.
The radiation with wavelengths from 10 nm to 180nm are referred to as a vacuum or extreme UV.
Frequency Range/ Velocity In a Vacuum
The velocity in a vacuum is 300, 000, 000 m/s.
Also are used for getting a sun tan, detecting forged bank notes in shops, and hardening some types of dental filling.
Positive health impacts the vitamin D, in our bodies. It produces frequently vitamin D in our body. It also impacts skin conditions. The UV is used in the treatment of the skin such as psoriasis. When it's exposed to the UV light, it slows the growth of the skin cells and relieves the symptoms.
Negative health impacts skin cancer. It's caused by the sun exposure. It states that as many as 90% of skin cancers are due to UV radiation. Another negative health impacts the immune system. When it's exposed too much to UV radiation, it harms the immune system to function unproperly by fighting diseases.
Summary about the Article
- Apple juice or cider are treated with UV light to reduce the levels of microbial pathogens.
- The urine of many species of rodent can strongly reflect UV light.
- UV-A ray is the least harmful ray, but it can damage the skin from aging. UV-B rays burn the skin and damage the humans eyes.
