The waves are usually emitted and absorbed by charged particles. This is exactly how the radio waves are usually transmitted in wireless communication. The waves have got both the magnetic as well as the electric field oscillating perpendicularly to each other and also perpendicular to the direction of wave propagation. Radio waves are usually in the range of 10 kHz to 100 GHz. The smaller ranges of the radio waves are usually used in the deep space telecommunication. However, the frequency as well as the wavelength of a propagated electromagnetic wave depends on its source.
The electromagnetic spectrum is the range of all the types of the electromagnetic radiation. Radiation is the type of energy that travels while spreading out as it goes. Some electromagnetic spectrum is invisible to the naked eye. However, they all have the properties of frequency and wavelength. The frequency of the electromagnetic spectrum is defined as the number of cycles of a wave that passes a particular point in one second. It is measured in Hertz. On the other hand, the wavelength of the electromagnetic spectrum is defined as the distance from the peak of a particular wave to the next one. It is measured in meters. The two attributes are however inversely proportional to each other. The longer the wavelength of the electromagnetic spectrum is, the smaller the frequency of the spectrum and vice versa. However, the shorter the wavelength of the electromagnetic spectrum, the more energetic is the light.
The frequency and wavelength of the electromagnetic spectrum are related in a precise mathematical formula. The wavelength is normally expressed by the Greek letter lambda (λ). On the other hand, the frequency of the electromagnetic spectrum is usually expressed as nu (ν). Their relationship is therefore expressed as:
a.) Radio frequency is the rate of oscillation of waves between the ranges of 3 kHz to 300 GHz. Very low
The periodic disturbances are usually both electric and magnetic fields. Electromagnetic waves normally travel through space at a relative speed of c =…
This research will begin with the statement that in electromagnetic induction, a current carrying wire induced a magnetic field around the wire. Cutting the field using a magnet will result to an induced emf, which is proportional to the rate of change of the magnetic field or speed at which the field is cut.
Marketing in the simplest form is defined as the activity and processes entailed in the creation, communication, delivering and exchanging offerings that have value for customers, clients and partners. In the endeavour to be effective in marketing, certain principles must be followed.
Electromagnetic radiation (EMR) is one of the key phenomena of electromagnetism, which behaves as photon particles or propagating waves travelling through space loaded with radiant energy (Abdo 2007). These waves characteristically travels at a speed of light in vacuum and in a straight line (Abdo, 2007).
Since there are a total of 28 electrons, half of them has a value of -½ and half of them has a value of +½. Therefore there are 14 electrons having a value of +½ ms
A5 For each of the following molecules, give the hybridization of the central atom
The universe comprises of millions of super clusters. These super clusters consist of hundreds of different sized galaxies. Of such a super cluster is our earth a part of. The super cluster consists of galaxies in the form of groups. The galaxy in which earth
The principles are easy to follow and simple and the fact that they not complicated to understand makes me even agree with them even more.
b. I would employ the principle of team work and cooperate with others in discussions and
The product can also imply to the services, which it is rendering to the consumers. As in the case of SleepWell, its products consist of bedding. For the products to fetch higher value, they must be of quality since
The aim of the assignment was to deepen the conceptual understanding of magneto static forces and fields. These objectives would be achieved by carrying out a series of experiments based on the study of magnetism and magnetic properties of different materials. The lab
