According to Bookrags.com, there are three types of solar radiation: ultraviolet, visible, and infrared.
Ultraviolet (UV) radiation is the type that gives people sunburns if they stay out in the sun without protection. The wavelengths are shorter than that of visible light, but longer than x-rays.
Visible light is the light that the human eye can perceive and uses to view objects. Unlike UV that cannot be seen or detected, this light can be observed.
Infrared radiation has longer wavelengths than any of the other two types of radiation. Most of the sun's energy hits the earth in this form. This type of radiation is readily employed by many industries and occupations. It is also used in night-vision devices.
Exposure to ultraviolet (UV) radiation is the leading cause of skin cancer, notes Cancer.net. So, follow these sun protection tips for healthier skin.
