the levels reaching the Earth’s surface. The sun emits energy over a broad spectrum of. wavelengths: visible light that you see, infrared radiation that you feel as heat, and ultraviolet. (UV) radiation that you can’t see or feel. UV radiation has a shorter wavelength and higher. energy than visible light.

The shorter the wavelength, the more energetic the radiation, and the greater the potential for harm. Ultraviolet (UV) radiation that reaches the Earth’s surface is in wavelengths between 290 and 400 nm (nanometers, or billionths of a meter). This is shorter than wavelengths of visible light, which are 400 to 700 nm.

The temperature decreases with altitude. Stratosphere: The stratosphere is found from about 7 to 30 miles (11-48 kilometers) above the Earth’s surface. In this region of the atmosphere is the ozone layer, which absorbs most of the harmful ultraviolet radiation from the Sun. The temperature increases slightly with altitude in the stratosphere. The highest temperature in this region is about 32 degrees Fahrenheit or 0 degrees Celsius.

UV-A is the least damaging (longest wavelength) form of UV radiation and reaches the Earth in greatest quantity. Most UV-A rays pass right through the ozone layer in the stratosphere. UV-B radiation can be very harmful. Fortunately, most of the sun's UV-B radiation is absorbed by ozone in the stratosphere. UV-C radiation is potentially the most damaging because it is very energetic. Fortunately, all UV-C is absorbed by oxygen and ozone in the stratosphere and never reaches the Earth's surface.

What type of radiation is absorbed by the ozone layer of the atmosphere? The harmful UV radiations coming from the sun are blocked by the ozone layer. Out of these the most harmful UV-C is almost completely blocked by nitrogen and oxygen, while UV-…b is absorbed by ozone.

The sun is a major source of ultraviolet rays. Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of visible light, ultraviolet rays, and infrared rays (also known as heat). Man-made lamps can also emit UV radiation, and are often used for experimental purposes.

In addition to their own resiliency, living things and the cells they are made of are protected from excessive amounts of UV radiation by a chemical called ozone. A layer of ozone in the upper atmosphere absorbs UV radiation and prevents most of it from reaching the Earth.

Stratospheric Ozone Layer. 1  The amount of UV rays the ozone layer absorbs varies depending on the time of year and other. natural events. Additionally, the ozone layer is thinner than it used to be due to ozone-. depleting chemicals used in industry and consumer products. These chemicals are being.

Simply put, ultraviolet radiation (also known as UV radiation or ultraviolet rays) is a form of energy traveling through space. Some of the most frequently recognized types of energy are heat and light. These, along with others, can be classified as a phenomenon known as electromagnetic radiation.

Fortunately for life on Earth, our atmosphere’s stratospheric ozone layer. shields us from most UV radiation. What does get through the ozone layer, however, can. cause the following problems, particularly for people who spend unprotected time outdoors:
