اشعه ماوراء بنفش و پوست در نگاهی کوتاه

Mohammad Baghaei

تابش فروسرخ یا به عبارت دیگر «اشعهٔ مادون قرمز» IR در علم فیزیک به قسمی از طیف امواج الکترومغناطیسی گفته می‌شود که طول موج آن‌ها بلندتر از دامنهٔ نور مرئی و کوتاه‌تر از دامنهٔ امواج رادیویی باشند. امواج فروسرخ در بازه بسامدی ۳۰۰ گیگاهرتز تا ۴۰۰ تراهرتز و طول موج ۱ میلیمتر تا ۷۵۰ نانومتر قرار می‌گیرند. مادون قرمز خود به سه زیر گروه تقسیم می گردد که عبارتند از : IRA دارای طول موج بین 760 الی 1440 نانومتر IRB دارای طول موج 1440 تا 3000 نانومتر IRC دارای طول موج 3000 تا 4000 نانومتر

Implementation of renewable energy resources in india-solar updraft tower

Neha Chouhan

This document presents information on solar updraft towers as a renewable energy technology. It discusses the components of a solar updraft tower, including the collector, chimney, and turbine. The collector covers a large area to heat air using the greenhouse effect. The heated air rises through the chimney due to buoyancy, powering a turbine. While construction costs are high, solar updraft towers provide renewable energy from sunlight with minimal operations and maintenance needs and no greenhouse gas emissions. They are well-suited for developing countries with ample land and sunshine.

AboutHydrology Slides

This document provides an introduction to solar radiation and its role in powering the water cycle. It discusses the composition and structure of the Sun, and how it produces radiation through nuclear fusion. While solar radiation is generally constant, it exhibits variations in the form of solar spots and an 11-year activity cycle. The amount of radiation emitted by any body is determined by the Stefan-Boltzmann law, which relates radiation to the body's temperature and emissivity.

SOLAR RADIATION MEASUREMENT

Vanita Thakkar

This document discusses different instruments used to measure solar radiation. It describes a pyranometer, which measures broadband solar irradiance on a planar surface using a thermopile sensor and glass dome. A pyrheliometer specifically measures direct solar irradiance and requires solar tracking to keep it aimed at the sun. Both instruments adhere to ISO and WMO standards and are used in meteorology, climatology and solar energy studies. A sunshine recorder measures the amount of sunshine at a location using either the sun or a clock as a timescale.

Reem Bakr

Scientists' ideas about the solar system have developed over time from ancient Greek philosophers like Aristotle and Ptolemy, who believed the Earth was the center, to Copernicus, who proposed the Sun was the center in the 16th century. Kepler later suggested elliptical orbits and Newton developed the law of universal gravitation. In the 18th-19th centuries, Herschel discovered Uranus and Hubble showed the universe is expanding, leading to the Big Bang theory. Major advances were made through improved telescope technology by Galileo and others.
