X10 xray vision4/7/2023 ![]() Data is easily accessible from anywhere, using Orexplore Insight or through export into the user’s favourite geological modelling tool. Orexplore’s drill core scanner, GeoCore X10, delivers digital geology at a touch of a button. Novel scanning technology is enabling the mining sector to completely rethink how geologic information is processed and analysed. X-rays, UV light, blue light, infra red and radio waves.Mikael Bergqvist describes how X-ray vision through the drill core can be used for enhanced mapping of mineral resources Arrange the following radiations in order of increasing wavelength: infra red, blue light, UV light, radio waves and X-rays.An X-ray machine produces a radiation of wavelength 1.0x10 -11 calculate:.A radio transmitter produces waves of frequency 1.0x10 8 Calculate the wavelength of the signal.Nuclear reactor explosions may lead to losses of lives.Similarly, radio waves can cause cancer, leukemia among other disorders. Therefore when exposed to the body in large doses, they can damage the body cells, cause skin burns or affect the eyes. Some of the electromagnetic waves like X-rays, ultraviolet and gamma radiation posses a lot of energy.Killing of cancer cells and other malignant growths. Radiography (identification of internal body structures e.g bones), cancer therapy, crystallography (study of crystal structure), pest and germ control and airport security ckecks. Photographic film, photocells, fluorescent materials e.g quinine sulphate.ĭetection of forgeries, skin treatment and killing of bacteria, spectroscopy and mineral analysis, making of clothes and a source of vitamin D.įluorescent screen and photographic film. Laser beams used in laser printers, weapon aiming systems, CD players. Vision (sight), photography, photosynthesis and optical fibre. Thermopile, bolometer, thermometer, photographic film.īurglar alarms, in military night vision missiles, cooking, heating and drying of grains, in green housing, in remote controls for TVs and VCD/DVDs, in photography. In telecommunication- radio broadcast, TV and satellite communication, cellular telephone, radar and navigation equipments etc.įrom special vacuum tubes called magnetrons within microwave ovens.Ĭrystal detectors, solid state diodes, antennae.įrom thermal vibration of atoms in very hot bodiese.g the sun. The table below summarizes the production, detection and applications of the various electromagnetic radiations: Can be emitted, transmitted and absorbed by matter.Ģ8.4: Production, detection and applications of electromagnetic radiations. ![]() Undergo reflection, refraction, diffraction, interference and polarization effects.Carry no charge (not charged) and are not deflected by a magnetic or electric field.The amount of energy possessed by an electromagnetic wave of frequency f is expressed as E= hf, where h is Plank’s constant and is equal to 6.63x10 -34 The wave equation c=f λalso apply for electromagnetic waves. Do not require material medium for their propagation.Travel in a vacuum with a speed of 3.0x10 8m/s. ![]() The following properties are common to all electromagnetic waves: Ģ8.3: Properties of electromagnetic waves When these waves are arranged in a certain pattern e.g in the order of increasing frequency or wavelength then we get an electromagnetic spectrum. They include visible light, radio waves, x-rays, infra red, ultraviolet, microwaves and gamma radiations. Electromagnetic waves are waves resulting from the interaction of oscillating electric and magnetic fields. We have seen that waves can be categorized either electromagnetic or mechanical in nature.
