Resonance – Journal of Science Education is a monthly peer-reviewed academic journal covering science education. It is currently being published by Springer Science+Business Media on behalf of the Indian Academy of Sciences and the editor-in-chief is Prof. B Sury. The journal was established in 1996.
The problem with this method is that when a tube of air is driven by a sound source, its length at resonance is not exactly equal to a multiple of the half-wavelength. [3] Because the air at the source end of the tube, next to the speaker's diaphragm, is vibrating, it is not exactly at a node (point of zero amplitude) of the standing wave.
In chemistry, the mesomeric effect (or resonance effect) is a property of substituents or functional groups in a chemical compound. It is defined as the polarity produced in the molecule by the interaction of two pi bonds or between a pi bond and lone pair of electrons present on an adjacent atom. [ 1 ]
Natural frequency, measured in terms of eigenfrequency, is the rate at which an oscillatory system tends to oscillate in the absence of disturbance. A foundational example pertains to simple harmonic oscillators, such as an idealized spring with no energy loss wherein the system exhibits constant-amplitude oscillations with a constant frequency.
The Franck–Hertz experiment was the first electrical measurement to clearly show the quantum nature of atoms.It was presented on April 24, 1914, to the German Physical Society in a paper by James Franck and Gustav Hertz.
The Pattali Makkal Katchi (PMK) party, a political party in Tamil Nadu, held a demonstration at Chennai for conducting the IIT-JEE and other national entrance exams in regional languages also, particularly Tamil in Tamil Nadu. [62] The PMK party filed Public Interest Litigation in the Madras High Court to conduct the IIT-JEE entrance exam in ...
However, resonance can also be detrimental, leading to excessive vibrations or even structural failure in some cases. [3] All systems, including molecular systems and particles, tend to vibrate at a natural frequency depending upon their structure; this frequency is known as a resonant frequency or resonance frequency.
The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...
