The Earth's ozone layer acts as a critical shield, absorbing most of the Sun's harmful UV-C and the majority of UV-B radiation. Monitoring these cycles is a vital area of ongoing scientific research.
Sun Electromagnetic Waves: Visible Light 400 to 700 Nanometers in Focus
Solar Activity and Cycles The Sun is not a constant emitter; its output varies on an 11-year cycle, moving from a solar minimum, characterized by few sunspots, to a solar maximum, marked by frequent solar flares and coronal mass ejections (CMEs). Impact on Space and Technology The Sun's influence extends far beyond the visible horizon.
The distribution of this energy follows a pattern known as blackbody radiation, peaking in the visible range due to the Sun's surface temperature of approximately 5,500 degrees Celsius. During these peaks, the spectrum of solar radiation can shift, with increased high-energy emissions posing greater risks to astronauts and sensitive electronics in space.

In contrast, high-energy X-rays and extreme ultraviolet (EUV) waves, primarily emitted during solar flares, are completely blocked by the atmosphere, but they can significantly heat and ionize the upper layers of the ionosphere, affecting radio communications. Visible and Infrared Light Visible light, ranging from roughly 400 to 700 nanometers, is the primary driver of photosynthesis, the process by which plants convert carbon dioxide and water into chemical energy.
