Sunray is the key factor in photosynthesis, a process vital for many living being on earth. The spectrum of the sun’s solar radiation is close to that of the blackbody with temperature of about 5800 k. The Sun emits EM radiation across most of the electromagnetic spectrum. The sun emits X-ray, UV ray, Infrared, visible light and even Radio waves. It in Space at the top of earth’s atmosphere at a power of 1366 Watts/m2 each composed of about 50% infrared light, 40% visible light, 10% UV light. Sunray is the main source of all power in the earth. It has huge power which is utilized various aspects using application of solar technology like architecture, urban planning, agriculture, electricity production. Ultraviolet Ray effect on the earth dangerously at present times increasing Green House Gases caused Ozone Hole. The environment and resource are of most concern with the present society and also for future generation. The resource of the country which are to be utilized adequately. We have to take up serious steps about the effect of Sunrays. Solar Radiation Management (SRM) controls the amount of the Sun’s radiation reaching the earth. SRM projects look into ways to increase the atmosphere reflectivity. By increasing the amount of reflectivity in the atmosphere, scientist could reduce the amount of energy that reaches the Earth’s surface. The field and study of Geography is earth and man. Geography is the only discipline that can pursue the study of environment and organism as whole. This paper deals with the different types, activity of the Sunrays and to alert present and future generation from the negative effect of the Sunrays, also Global Warming. By reservation of Sunrays we can protect and develop nature, Society as well as our existence of life circle.
