The correct answer is E. Ultraviolet, visible, and infrared radiation.
Solar radiation is a form of electromagnetic radiation that is emitted by the Sun. It is a mixture of all wavelengths of electromagnetic radiation, from radio waves to gamma rays. However, the majority of solar radiation that reaches the Earth’s atmosphere is in the form of visible light, ultraviolet light, and infrared light.
Visible light is the light that we can see with our eyes. It has a wavelength of about 400 to 700 nanometers. Ultraviolet light has a wavelength of about 100 to 400 nanometers. It is invisible to the human eye, but it can cause sunburn and skin cancer. Infrared light has a wavelength of about 700 nanometers to 1 millimeter. It is also invisible to the human eye, but it can be felt as heat.
The Earth’s atmosphere absorbs some of the Sun’s ultraviolet and infrared radiation. The rest of the radiation reaches the Earth’s surface, where it is used by plants for photosynthesis and by humans for a variety of purposes, such as heating, lighting, and generating electricity.
The amount of solar radiation that reaches the Earth’s surface varies depending on the time of year, the latitude, and the weather conditions. In general, solar radiation is more intense at the equator than at the poles. It is also more intense during the summer than during the winter. Clouds can block solar radiation, so on cloudy days, there is less solar radiation reaching the Earth’s surface.
Solar radiation is a vital part of life on Earth. It provides the energy that plants need to grow, and it is also a source of energy for humans. However, too much solar radiation can be harmful to human health. It is important to protect yourself from the sun’s harmful rays by wearing sunscreen, sunglasses, and a hat.
