Wind blowing westward and toward the Equator from the subtropical high-pressure belts toward the intertropical convergence zone is known as the trade wind (ITCZ). Over the oceans, it is stronger and more persistent than over land, resulting in mostly cloudy skies with shallow cumulus clouds or bright skies, which make trade-wind islands popular tourist destinations.

Whenever the temperature of the Earth’s surface rises, it creates a powerful upward wind, which carries water droplets aloft, in which they freeze and fall again. The rapid movement of falling water droplets and rising air causes lightning and sound to be produced. This is referred to as a thunderstorm. It is especially common in

The Doppler effect is a fascinating phenomenon that is observed in the propagation of waves. It deals with the apparent distortion that happens in the propagation of waves when the source or the observer of the wave are in relative motion.    According to the Doppler effect, the frequency of the wave has an apparent

As the name implies, Pulse Amplitude Modulation (PAM) is an analogue modulation scheme in which the amplitude of the pulse carrier fluctuates in accordance with the current amplitude of the message signal. The amplitude of the original signal will be followed by the amplitude of the pulse amplitude modulated signal as the signal traces out

The programming or numeric computing platform analyses the signals and indicates the algorithms based on the overlapping signals. Overlapping of signals is mainly caused due to three factors:  Formation of the propagation. Numerous targets. Compound physical effects of the propagation path. The issue of overlapping signals takes place in each frequency domain and time. Time

Noise pollution is a threat that is difficult to detect. It cannot be seen, but it is nonetheless present, both on land and beneath the ocean’s surface. In the context of noise pollution, any unwanted or disturbing sound that has an adverse effect on the health and well-being of humans and other organisms is considered

What Is the Doppler Effect? Christian Doppler, an Austrian physicist, first propagated the Doppler effect. He found that fluctuations between the source and detecting participants affect the frequency of light and sound.  In physics, the doppler effect stands to explain all kinds of waves. According to this effect, the frequency of waves, such as sound

The Doppler effect is a natural phenomenon we experience in our everyday life. The phenomenon is even found useful in different situations.  We use the Doppler effect to detect an approaching bus or a train. In the hide and seek game, we perceive the sound of our opponent because of the Doppler Effect.  But what

Introduction Young successfully carried out an experiment to determine the wavelength of light in 1801. Young’s problem was that the normal light sources of the day (candles, lanterns, etc.) couldn’t be used as coherent light sources. Young’s solution involves letting sunlight into the room through a pinhole in a window shutter. The pinhole beam was

What is the Doppler effect? When an object is moving with respect to the observer, then a phenomenon is observed, which is known as the Doppler effect. A typical example of the Doppler effect is when an ambulance comes closer to you from the back, and the siren is on. You will observe an increase
