1. Define land resource surveying methodology. Identify the two approaches in land resource surveying methodology. 2. Discuss the contributions of Aristotle‚ Louise Deguerre‚ Argo‚ Loussedat and Deville in enriching the science of topographic surveying. 3. The atmosphere influences EMR in two ways. Discuss them. 1. According to Professor Masaka (2011) Land resource survey methodology can be defined as the starting point for any natural resource management policy has to be an inventory of

NT1310 Unit 7 Exercise 1 1. Crosstalk: A disturbance caused by electromagnetic interference‚ along a circuit or a cable pair. A telecommunication signal disrupts a signal in an adjacent circuit and can cause the signals to become confused and cross over each other 2. Waveguides: A circular‚ elliptical or rectangular metal tube or pipe through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined

microwave. Introduction Thin Film Interference When plane electromagnetic wave of wavelength λ is incident on a dielectric surface‚ part of the electromagnetic wave is reflected‚ and part of it is transmitted. If the dielectric is thin‚ i.e. its thickness t is comparable to λ‚ the plane electromagnetic wave will be reflected again at the second dielectric surface‚ as shown in Figure 1. [pic] Figure 1. Electromagnetic waves incident at angle θ1 reflected from the top and bottom surfaces

Using colorimetry to find the order of a reaction introduction Coloured solutions absorb some of the wavelengths in the visible region of the electromagnetic spectrum. A colorimeter can be used to measure the amount of light absorbed by a solution (the absorbance) and this is proportional to the concentration of the coloured species present. In this experiment you will use a colorimeter to investigate the reaction between bromine and methanoic acid:- Br2 (aq) + HCOOH (aq) ↓ 2Br-

discovered. By the early 19th century‚ evidence that light is a wave had grown very persuasive. In 1873‚ James Clerk Maxwell predicted the existence of electromagnetic waves and calculated their speed of propagation. This development‚ along with the experimental work of Heinrich Hertz starting in 1887‚ showed conclusively that light is indeed an electromagnetic wave. The wave picture of light is not the whole story‚ however. Several effects associated with emission and absorption of light reveal a particle

diffraction and interference are observed‚ waves are involved. Waves do not have mass or charge. Photons All electromagnetic radiation consists of photons. A photon is a packet of energy‚ or a quantum of electromagnetic energy. Gamma-photons are the most energetic out of all the types of photons. The energy of a photon is directly proportional to the frequency of the electromagnetic radiation of which it is a part of‚ so high frequency radiation means high energy

(13 points) A Doppler radar is an important tool used to measure the velocity and direction of a moving object. The Radar actually has transmitters that produce and release electromagnetic waves in the form of microwaves or radio waves. These waves are sent out and when they reach something they reflect or
