What is ultraviolet radiation where does it come from what is uv index and how is the uv index determine?
Ultraviolet (UV) radiation is a type of electromagnetic radiation that comes from the sun and can also be produced by artificial sources like tanning beds and some lamps. The UV index measures the level of UV radiation from the sun at a particular place and time, which helps to inform people about the potential risk of harm from sun exposure. The UV index is determined based on factors like the angle of the sun, cloud cover, and ozone levels in the atmosphere.
How are uv rays are harmful?
UV rays are very harmful. It is because of the high frequency that they carry.
What ozone layer do?

What is the UV index?
The UV index is a measurement of the strength of ultraviolet (UV) radiation from the sun at a particular place and time. It helps people understand the potential health risks of exposure to UV radiation, with higher values indicating greater risk of harm from sun exposure.
What affects uv rays?
Ozone affects UV rays. These are harmful rays of the sun.
How bad is a UV index of 10?

How can one accurately measure the UV index?
To accurately measure the UV index, one can use a UV index meter or a smartphone app that provides real-time UV index readings based on location and time of day. UV index meters measure the intensity of ultraviolet (UV) radiation from the sun, which can help individuals determine the level of sun protection needed to prevent skin damage and sunburn.
Can you tan when the UV index is 3?
