Visible Light Human Eye
455 wordsNaive realism is just a way of looking at the world. Also called common sense realism, things are perceived directly as they are. True naive realists would never sum up or analyze their views, because they do not consider them views but the way things obviously are. However, I will do my best to illuminate them: "I, the naive realist, am a human being. There is the physical world, the space where everything exists and the time in which everything happens. There are many things in this physical w...

Fibre Crystal Mid Infrared Lasers
1,998 wordsFibre crystal mid-infrared lasers As we know, a laser is an optical oscillator made out of a gas, liquid or solid with mirrors at both ends (see, e. g. , The Computer Language Company Inc. , 2007 b). To make the laser work, the material is pumped with light or electricity. This pumping has excited the electrons and has caused them to jump to more high orbits. Some electrons do spontaneously drop back to lower energy levels what releases photons (i. e. quantum's of light). The photons do then sti...

Dust Particles Blue Light
1,256 wordsExploration of a Natural Colour Phenomenon Why does the sky colour change? To answer this question, one should be aware of the Earth's atmosphere, and light. What is the atmosphere? The sky is filled with air which is a mixture of tiny gas molecules and small bits of solid stuff, like dust (Why Is the Sky Blue? ). The air constitutes the atmosphere, a gaseous shell surrounding the Earth and some other planets. The main gaseous components of the atmosphere are nitrogen (78. 09 %) and oxygen (20. ...

Endoplasmic Reticulum Electron Microscope
1,979 wordsExplain With Aid Of A Diagram The Explain With Aid Of A Diagram The Working Of The Electron Microscope The diagram below shows a picture of an electron microscope. This is a type of microscope that makes use of a beam of electrons rather than visible light. Because the wavelength of electrons is much smaller than the wavelength of visible light, an electron microscope not only gives a high magnification but it also has high resolution. This means that details can be seen clearly. An electron mic...

Radio Waves Light Waves
335 wordsRadio astronomy uses radio waves to study regions of space. Radio waves are a form of electromagnetic radiation like visible light waves only with much longer wavelengths. Visible light waves are oscillating electromagnetic signals with wavelengths of less than one millionth of a metre, whereas radio waves have wavelengths in the range of a few millimetres to several metres. Radio telescopes gather and concentrate the radio waves from an astronomical source. The signal received is then electroni...
