Helium Sophia bolg Elementors Pierre Janssen and Norman Lockyer discovered helium. Pierre Janssen was born on February 22‚ 1824‚ Paris‚ France and died on December 23‚ 1907. He became permanently lame after an incident from his childhood. He could not go to school because of that but did have to start working as a bank clerk due to financial problems. He graduated from the University of Paris in 1852 and in 1865 he became professor of physics at the École Speciale d’Architecture in Paris.While

atmosphere. On days when the atmosphere contains water vapor‚ particles of dust‚ and others bigger than nitrogen and oxygen‚ the sky appears less blue compared to clear dry days. Why do we have Blue Sky? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere‚ most of the longer wavelengths pass straight through. Little of the red‚ orange and yellow light is affected by the air. However‚ much of the shorter wavelength light is absorbed by the gas

Fading channel is modeled as a Gaussian random process. 2. The transmitter output is convolved with fading channel to obtain the faded output. 3. The faded output retains the characteristics of the original signal but highly attenuated. The faded output and the original output can be observed using

contains 18 protons and 18 electrons with 22 neutrons. It has an atomic mass of 39.948. Suspected to be present in the atmosphere in 1785 by Henry Cavendish‚ Argon wasn’t actually discovered until 1894 by William Ramsay‚ a Scottish chemist‚ and Lord Rayleigh‚ an English chemist. Argon makes up about 0.93% of the Earth’s atmosphere. It is a byproduct of the product of nitrogen and oxygen. Per year‚ it is commercially produced around 700‚000 tons globally. Argon is a colorless‚ odorless‚ tasteless noble
