Electromagnetic spectrum

Spectrophotometry is a method in which organic and inorganic substances are identified or characterized by the use of electromagnetic radiation. Electromagnetic radiation not only includes light (or photons), but thermal energy as well. While the electromagnetic spectrum consists of wavelengths between gamma radiation and the Far IR, most spectrophotometric methods rely on the UV and visible region. In order to use spectrophotometric methods, the sample being analyzed must be able to absorb the…

These types of energy are measured on an electromagnetic spectrum, which sub-classes the type of energy based on their wavelengths. The higher the wavelengths the higher the energy will be ranked in the seven stages. Next, Electromagnetic Energy is all around us and we are basically waves traveling through space at the speed of light. Therefor Electromagnetic Energy can happen because of an electromagnetic field, forcing an atomic particle to move. Electromagnetic energy gives off wavelengths,…

ROLE OF ELECTROMAGNETIC RADIATION AND BEER LAMBERT’S LAW Electromagnetic radiation Electromagnetic radiatio :– it is a form of energy whose behavior is described by the properties of particles and wave. Few properties of electromagnetic radiation for eg. Its refraction when it passes from one medium to another are explained best by describing light as a wave. Some other properties such as emission and absorption are better explained by treating light as a particle. The correct or exact nature…

When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

Light is an electromagnetic radiation that can be detected by humans. Electromagnetic radiation happens in an extremely large range of wavelengths from gamma rays to radio waves. Within that spectrum the wavelengths visible to humans are few. Light is very difficult to define, in the sense that scientist have been arguing weather light is a particle or a wave. Many experiments have been done to proof weather light is a particle or a wave. The truth is that light sometimes acts as a wave and…

sound share many common aspects. Today, we will study some of notable similarities and differences between the two. We can perceive both light and sound. We see through eyes and hear through ears. Both light and sound are waves. Light is an electromagnetic wave whereas sound is a mechanical wave. Light is created by interaction of electric and magnetic field. It does not require any medium for propagation, so it can propagate in free space. On the other hand, sound wave requires physical medium…

Observation Why do shadows form? Why does light change directions when it hits a mirror? Why can't you see sun rays in the atmosphere? Why does a sun ray turn into a rainbow when going through a prism? Why do mirages happen? Why does an object's appearance (color) change when in different color light? How do a bunch of tiny colored lights in a television make up just one color? Why in water, does it look like a straw is bent but it really isn't? What happens to a piece…

” This is the light that is divided up into six elementary colors; red, orange, yellow, green, blue violet. This is true when you place a thick piece of glass in the sunlight and a rainbow band of colors appear. These colors are put onto a light spectrum with its shortest wavelength are violet and its longest wavelength ending in red. Well now you must be wondering what a wavelength is. A wavelength, “the distance between two adjacent similar points of a wave such as from crest to crest or from…

has more energy than low frequency. Explanation: For this hypothesis, we found that our calculations were wrong and we tested this by using the electromagnetic spectrum: radio wave, microwave, radiation, infrared, visible light, ultraviolet, X-rays and gamma rays. We went outside and made a simulation by walking and each group was one of the spectrums and we looked at how many more laps one group did than the other and we found that radio waves have the lowest frequency and gamma rays have the…

1a) The incandescent bulb produced a continuous spectrum because all wavelengths were observed. Rutherford’s model predicts that the spectrum of hydrogen should be continuous as well. b) During the demonstration, a continuous spectrum was observed for incandescent light and a line spectrum was observed for hydrogen; therefore, my observations seem to contradict with Rutherford’s model. Rutherford hypothesized that atomic spectra should always be continuous because he believed that electrons…
