Wave motion and speed of a wave

What is amplitude modulation?  It is a flexible device used for electronic communication, usually through a radio transmitter. In amplitude modulation, a wave’s amplitude (signal strength) varies in proportion to that of a signal, such as a sound signal. Amplitude modulation is the process by which a wave signal is transmitted by changing the signal […]

Matter wave duality is one of the most fundamental theories which gives a direction to quantum physics from classical physics. It describes the dual nature of matter. That is, matter can behave like both matter and wave. This gives rise to the dual nature of the matter. The phenomenon of a beam of light that

Introduction A wave is the movement that occurs in a medium from one point to another when a body comes in contact with it. For example, consider that when you throw a rock or stone into a river, patterns are created in a circular motion through the point where the rock hits the water. Here

Sound A sound is a vibration that propagates or travels in the form of a mechanical wave through any medium. A solid media, a liquid medium, or a gas medium can all be used to propagate or travel waves. Sound travels the fastest in solid mediums, slightly slower in liquids, and the slowest of all

Huygen’s theory talks about the wave nature of light. Huygen found an error with Newton’s statement. On observing the spreading of light through a dark room when passing through an obstacle, the intensity of light decreases with the distance of the light path. Thus, Huygen proposed that light has a wave nature, which finally concluded

The rate at which a wave propagates in any medium is known as its phase velocity. This is the speed at which the phase of any one of the wave’s frequency components travels. Any specific phase of the wave (for example, the crest) will seem to travel at the phase velocity for such a component.

Communication System is a group of individual telecommunication networks, transmission systems, tributary stations, relay stations, and terminal equipment usually capable of interconnection and interoperation to form an integrated whole. Modulation is a process by which information is encoded from a message source to optimise it for transmission. Frequency modulation is the coding of information in

The concept of waves has always been a fascinating topic. When we talk of the fundamental harmonics and the modes, one needs to have a digital concept of what a wave is composed of. A wave is a typical disturbance graphically represented using nodes, amplitude and frequency. It is also closely related to the wavelength.

Amplitude measures the change of a periodic variable in a period. The method of varying properties of a periodic waveform is termed modulation. Modulation signal contains information that is to be transmitted. Modulation functions to impress the information into carrier waves. Amplitude modulated wave examples can be audio signals or sounds, video signals or moving

Christian Huygens (1629-1695), a prominent Dutch physicist, published a dissertation on the wave theory of light in 1678 called Traite de la Lumiere. He stated in this paper that the wavefront of a propagating wave of light conforms to the envelope of spherical wavelets coming from every point on the wavefront at every instant (with
