Emission Of Radiation

Alpha radiation occurs when there are most neutrons in an atom, which causes the atom to turn into an isotope. Alpha radiation is formed due to the atom not being able to sustain the extra neutrons in the nucleus. The atom undergoes radioactive decay, which will emit helium particles (alpha radiation) which consists of two protons and two neutrons in order to stabilize itself.

Laser is a shorter term for “Light amplification of stimulated emission of radiation”. Laser is device that generate powerful and coherent light. Laser functions by the process of amplification of light and simulated emission of radiation. Laser are formed in all types of matter gas, solid and liquid, example of lasers that are commonly used are “Supermarket Scanning Systems, DVD player, medicine usages, lighting shows, laser printers and Communications system” just to name few. McComb (1988, p.3) demonstrated how laser work by referring to neon tube that activity atom and photons to make laser light. Also, McComb (1988, p.3) refers to

Every element and subsequent atom associated emits light; also know as electromagnetic radiation, when in an excited state. Analyzing this emitted light can give insight to the makeup and characteristics of them. The light given off by an energetically excited

The base of the light triangle, b, was measured first. Then, the light positions, a, were measured f=or the first order (m=1) and second order (m=2) light beams to determine the angle Ɵ for each. This data was organized in an Excel table and used to find the wavelength, λ, of the laser through Equation 1. This value was then compared to the theoretical value for wavelength of the laser, which was 6.328x〖10〗^(-7)m, and the percent error was calculated between the two.

The word laser is an acronym for, “Light Amplified by Stimulated Emissions of Radiation”, this means that all the lights in a laser have the same wavelength. Within a century of the laser being invented it occupied a major role in scientific research, medicine, industry, and even daily life. Lasers are used in the medicine field for procedures such as, laser eye surgery, heart, stomach, and intestinal surgeries. These procedures laser procedures are said to be harmless. Major factory industries use lasers to cut many things ranging from thin

If you've ever in your life you've watched or read anything sci-fi, there's little doubt that a laser has been involved. Every single video game I play where there is a big sci-fi influence on it, there's a laser. I just bought are reviewed No Man's Sky. Most of the weapons and mining tools are energy based laser weapons. But that is just science fiction -- for now.

Usually an excited state can take the form of the electron bouncing from its start energy level or annual also called the ground state. The excited states that are found in the atoms which are in molecules are really crucial for some chemical reactions. The excited electron does not stay in the excited state for a long time, in a while it goes down back to the ground state. When an electron goes down from the excited state, its energy decreases in the form of light, this process is called emission (What is an Excited

The laser was invented by Theodore H. Maiman on May 16, 1960 at Hughes research laboratory in California (Early History, 2). The laser, which stands for Light Amplification by Stimulated Emission of Radiation, has three main components: the pump, the laser medium, and the optical resonator. The pump sends energy into the laser

In order to understand laser shows, you need to understand lasers. The first working laser was created by Theodore Maiman, who placed a ruby rod, a fully reflective mirror on one end, a partially reflective mirror on the other, with a high-intensity lamp wrapped around the ruby rod into a cylinder to create a laser beam. When the lamp was turned on, it excited the electrons in the ruby rod. Excited electrons emitted photons,

We as a species have done many amazing things. We have clawed and fought our way to the top of the food chain. We put ourselves above animals and organized a society more advanced than anything else in the history of the earth. We started out on land. We built cars and trains. But we were limited to just the land. Then we took over the sea. We created boats and massive ships of steel. There was one more place to control. The air. We created vehicles that could take us higher than anybody could have possibly imagined. But we can’t stop there. In approximately five-billion years the sun will expand, engulfing the Earth, ending all life. About four-billion years before that though, it will start to expand. The oceans will boil, the land will be scorched, and only the hardiest creatures living underground will survive. That is why we need to search for a new home. And I believe we can develop the technology to get us there. In recent years we have made numerous technological advancements. On December

The purpose of this experiment was to determine a series of external standards using Atomic Absorption (AA) and Flame Atomic Emission (FEA) spectroscopy. The principles of Atomic Absorption spectroscopy relies on the ability to distinguish one atom from another with great sensitivity as explained in Quantitative Chemical Analysis by Daniel Harris1. Specifically, this high precise determination can be achieved when specific wavelength of light is generated by a hollow-cathode lamp. The light emitted by the lamp travels through the flame until it reaches the mixture of neutral atoms. The electrons of the desired neutral atom gets excited to a certain energy level. As they return to the ground state, the energy emitted in the form of photons is analyzed by the detector. The photomultimeter tube (PMT) inside the detector amplifies the incoming photons into a cascade of electrons, which then is read by the computer and converted it into a function of absorbance.

Though the guns used in commercially played laser tags have lasers they are not used in actual mechanism of the game, they actually use infrared to register hits. Infrared has its own cool properties such as it gets scattered in very short

This optical amplification is started from some emission but it is not exposed yet until Albert Einstein proposed in 1916. After that, the things became more seriously after 1954 when Townes and Arthur Schawlow also with Gordon Gould proposed laser action, then not long after 4 years, in 1960, first laser was build by Theodore Maiman. Besides that, Gordon also derived the word laser from “light amplification by the stimulated emission of radiation”. The laser developer look amplification is very important as a step to build a laser, so these people make one advance to develop amplifiers from semiconductor laser to be used as light sources. This is because of semiconductor have high gain. Laser made up with high gain and low noise is

Linear accelerators utilise light in a different manner. This technology utilises high Radio-Frequency electromagnetic waves to accelerate charged particles inside of a tube which directs these particles to collide with a heavy metal target. The results of these collisions is the release of x-rays in the form of light as photons which are then directed to the patient's tumor.
