Electromagnetic spectrum

What does radiation have to do with a cellular device? Here I’ll tell you. According to Environment, Health, and safety online, “A cell phone or cellular device operates with radio frequencies. Which is a form of electromagnetic energy that’s located on the electromagnetic spectrum between FM radio waves and waves used in microwaves, ovens, radar, and satellite stations.…

Since all of the different types of electromagnetic waves travel at the same speed (~3x108 m/s), the only factor to change is the wavelength (λ) or its inverse, the frequency (μ). To acquire this value, the ideas of electromagnetic and cosmic radiation have to be accounted for. Because all objects in our universe and anything between us and the receiving planet emit some sort of electromagnetic radiation, extensive research has been put into determining the range…

emission of electromagnetic waves. The waves hold energy away from releasing object. For a normal temperature, the radiation is in the infrared region of the electromagnetic spectrum. The relationship ,conducting the net radiation from a hot object is called,” Stefan Boltzmann Law.”In 1879, it empirically obtained by Josef Stefan. In 1884, it was obtained theoretically…

universe extremely different or remarkably unrecognisable from our own. Light creates space, wherein it indirectly generates time. On a universal scale, our the sum of thoughts, words and actions churn the wheel of Karma. (The Moral Principle and/or Spectrum of Cause & Effect) Time progresses in accordance with the forms, we take. In the absence of Self-Realisation, this continues until the dissolution of the cosmos at the lateral end of space-time. At which point, we dissolve along with it.…

In order to find the answer to this question, it must be broken down. What are photons? How does gravity affect light? What is a black hole? A photon is typically seen as a particle or wave representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass. Photons are currently best explained by quantum mechanics. However, it is important to know that photons have both the qualities of waves and particles…

Violet is at the short-wavelength end of the visible spectrum, 400nm, so it reflects the short wavelengths and absorbs longer wavelengths. However, red light is at the long-wavelength end of the visible spectrum, 700nm, so it reflects long wavelengths and absorbs shorter wavelengths. The shorter the wavelengths, the higher the light energy is so the temperature of the colours near the ‘violet’ end of the visible spectrum increases more drastically than the colours near ‘red’ end. Therefore…

Types of Spectroscopy used in Organic Chemistry 1.1 Introduction Spectroscopy is the study of the interaction between matter and light (electromagnetic radiation) (Crouch & Skoog, 2007). It is often phrased as the light of knowledge (Reusch, 2013). In the past, spectroscopy started by the study of visible light dispersed according to its wavelength by a prism (Anon., n.d.). Now, with the knowledge of light having both wave-like and particle-like characteristics, with given frequency or…

Spectroscopy is the study of how matter and electromagnetic radiation interact with one another. In this experiment, we are observing and recording the emission of photons with wavelengths on the visible light spectrum. To understand…

electron beam is focused into a fine probe, which is scanned across the surface of the specimen with the help of scanning coils is shown in Fig. 2.6. Each point on the specimen that is struck by the accelerated electrons emits signal in the form of electromagnetic radiation. Selected portions of this radiation, usually secondary (SE) and/or backscattered electrons (BSE), are collected by a detector and the resulting signal is amplified and displayed on a TV screen or computer monitor. The…
