an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like in its behavior‚ whereas toward the long wavelength end of the spectrum the behavior is mostly wavelike. The visible portion

Flame Tests Atomic Emission and Electron Energy Levels AES‚ or atomic emission spectroscopy‚ is a method which chemically analyzes the particular wavelength of a sample element to identify and determine the abundance of this certain element. The wavelength of the atomic spectral line unveils the identity of the element while the emitted light intensity is proportional to the number of atoms in the element. The flame test is also a very effective way to identify an individual element. The color

Practical 3 Absorption Spectra and the Beer-Lambert Law INTRODUCTION Electromagnetic radiation can be described in terms of frequency (V) and wavelength (λ). Absorbance is the capacity of a substance to absorb radiation and transmittance (the fraction radiation at a specified wavelength that passes through a sample) is physical properties that all molecules have. The purpose of experiment one was to find the maximum absorbance (λmax) occurred for both bromophenol blue and methyl orange by

are located remotely apart and the electromagnetic radiation serves as a link between the sensor and the object‚ the sun being the major source of energy illuminating the earth. The part of this energy is reflected‚ absorbed and transmitted by the surface. A sensor records the reflected energy. Remote Sensing is performed using an instrument‚ often referred to as a sensor. Most of the remote sensing instruments record electromagnetic radiation (EMR) that travels at a velocity of 3x10^8 m/s from

Microwave power transmission (MPT) is one of the applications of microwaves to transmit power from one place to another place without the need for wires. It is the type of the Electromagnetic Radiations‚ one of the wireless energy transfer methods. Introduction: Firstly‚ we will talk about the term Microwaves‚ Microwaves can also be termed as Radio waves having wavelengths ranging from one millimeter to one meter and the frequencies from 300MHz to 300GHz. These are also known as millimeter waves

1. Testicular cancer is a common disease associated with the male reproductive system. The major symptoms associated with the disease are lumps and/or enlargements of either testicle‚ aches in the groin or abdomen area and collection of fluids in the scrotum. Other symptoms include enlargement or tenderness of the breasts and back pain. This cancer is diagnosed typically after the discovery of a lump or swelling in the testicles. The swelling or lump is usually discovered when a man gives himself

LABORATORY ACTIVITY FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will

in ultra-violet light. Wood has been described as the "father of both infrared and ultraviolet photography" because of the discovery of electromagnetic radiation beyond the visible spectrum and the development of photographic emulsions. He was the first to intentionally produce photographs with both infrared and ultraviolet radiation. He also coined the slightly surreal glowing appearance of foliage in infrared photographs as “Wood effect”. He identified a very low ultraviolet reflectivity
