Ultraviolet waves are a part of the electromagnetic spectrum and lie in the region of short-wavelength radiations. It resides between X-Rays and the visible light and has a wavelength of 10 – 400 nm, which is shorter than that of visible light but longer than the wavelength of X-rays. As it has a wavelength shorter […]

Introduction An electromagnetic wave consists of an electric and a magnetic wave in which electric and magnetic field vectors are perpendicular to each other and they are also perpendicular to the direction of propagation of the wave. This nature of electromagnetic waves is known as the transverse nature of electromagnetic waves. Reflection Reflection means a

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
