Introduction Visible light is electromagnetic waves that enable us to view the world around us. The various electromagnetic waves include infrared rays, microwaves, gamma rays, and ultraviolet rays. Every wave has a distinctive characteristic, range of distinct frequency and wavelength, and different uses. Maxwell was the first scientist to predict the presence of electromagnetic waves. […]

Electromagnetic radiation is the transfer of energy at the velocity of light across free space or a solid medium in the form of electric and magnetic fields that make up electromagnetic waves like radio waves, visible light, and gamma rays. The intensity and frequency v of the time fluctuation of the electric and magnetic fields

Gamma rays have the shortest wavelengths and the highest energy levels of any electromagnetic wave. They are created by the universe’s hottest and most energetic objects, including neutron stars and pulsars, supernova explosions, and black hole regions. Nuclear explosions, lightning, and the less dramatic activities of radioactive decay all produce gamma radiation on Earth. Typical

Introduction Bandwidth of signals refers to the difference between the frequencies of the upper band and the lower band in the continuous band frequency. Bandwidth of signals basically refers to the frequency range at which the electronic circuit can operate efficiently and without interruption. For example, if the amplifier has a bandwidth of 2800 Hz,

Space wave propagation is a type of radio wave propagation in which radio waves go directly from the transmitting antenna to the receiving antenna or are reflected from the ground. In general, line of sight communication is used in space wave propagation to achieve direct signal transfer. The tropospheric area of the atmosphere is used

The Huygens principle, which is based primarily on the nature of light, was discovered by the Dutch mathematician Huygen in 1678. This principle is mainly used to describe rectilinear and spherical wave propagation. Also, in this theory, light has been described as a type of disturbance. Also, it has been said that with the propagation

It is necessary to define radio wave propagation in order to comprehend the meaning of skywave propagation. The behaviour of radio waves as they spread from one location to another or into different areas of the atmosphere is known as radio wave propagation. The categorisation of these waves is as follows: 1.The propagation of ground

Sky and space wave propagation Space wave propagation and skywave propagation are directly related to radio wave propagation. They are used to communicate at high and low frequencies.   To understand more about skywave propagation, space wave propagation, application of space wave propagation and space wave propagation limitations, we need first to understand its type.

Introduction What do you understand from the terms Sky and Space wave propagations? These two are the types of radio wave propagation along with ground wave propagation. In sky wave propagation electromagnetic waves were reflected from the ionosphere in the atmosphere. Space wave propagation is transmitted from one antenna to another antenna in the troposphere.

Electromagnetic waves, often referred to as electromagnetic radiations, can be described in terms of overlaid waves of an electric field and a magnetic field within space with the directions of propagation parallel to each other. In simple terms, electromagnetic waves are the result of oscillations by electric and magnetic fields. The direction of propagation of
