lives‚ especially in tropical regions as information from satellites is used to track hurricanes as they develop. The first satellite completely dedicated to weather forecasting was developed by NASA. The satellite was named TIROS-I (television and infrared observation satellite) and was launched on 1st April‚ 1960. The weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting‚ covering the entire Earth asynchronously

CIRCUIT IDEAS REMOTE-CONTROLLED FAN REGULATOR Dr C.H. VITHALANI sing this circuit‚ you can change the speed of the fan from your couch or bed. Infrared receiver module TSOP1738 is used to receive the infrared signal transmitted by remote control. The circuit is powered by regulated 9V. The AC mains is stepped down by transformer X1 to deliver a secondary output of 12V-0-12V. The transformer output is rectified by full-wave rectifier comprising diodes D1 and D2‚ filtered by capacitor C9 and regulated

NIGHT VISION TECHNOLOGY ABSTRACT A night vision device (NVD) is an optical installment that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies‚ but are available to civilian users. The term usually refers to a complete unit‚ including an image intensifier tube‚ a protective and generally water-resistant housing‚ and some type of mounting system. Many NVDs also include sacrificial lenses‚ IR illuminators

process. First‚ sunlight radiates from the sun‚ through space‚ to Earth’s atmosphere. Second‚ sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land‚ which in turn makes it warm. Third‚ greenhouse gases trap infrared rays that are remitted into the atmosphere. Finally‚ the gas then absorbs the light and is remitted back to the Earth’s surface and warms it even more. Left on it’s own this natural process

above what it would be in the absence of the gases.[1][2] Solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface‚ which then emits this energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases‚ which in turn re-radiate much of the energy to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse‚ but

What is the impact of human activity on the natural environment? Answer: Humans are a part of the natural environment. Unfortunately‚ we have not yet learnt to moderate our activities in such a way as to help the environment. Human activities often lead to degradation of the environment. Impacts of humans include: • pollution - land‚ freshwater creeks and rivers‚ seas and oceans‚ and air • deforestation and destruction of habitats • endangerment and extinction of flora and fauna species

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula
