relative frequency

As the threshold of audibility varies with frequency, sounds of the same intensity but different frequencies are found to differ in loudness. Therefore, another unit of loudness is defined. This unit measures the intensity of a sound relative to a reference tone of def..

Question: The relation between wave velocity 'v', frequency 'f ', and wavelength ' l ' is ______. 1. 2. 3. 4. Answer: ..

The four important terms used in the study of waves are Wavelength, Amplitude, Frequency and Wave velocity. Wavelength ' l ' is the distance between two consecutive points on the wave which are in the same phase. (same phase means same state of vibrations) Amplitude is the maximum displac..

. The distance travelled by the waves relative to the source in 1 second. If f is the frequency of the waves produced by the source, then f waves are accommodated in a distance S l A l . Since the observer recedes by a distance b in 1 second, the relative velocity of t..

. The prongs are again drawn inwards. This process repeats and the prongs vibrate. The frequency of vibration is a constant, depending on the parameters related to the fork. A long flexible thread is attached to the end of a prong and the thread is passed over a frictionless pul..

. Initially, the path lengths are adjusted to be equal. The outer tube is pulled out till the sound intensity becomes minimum. The distance through which the tube has been slided will be l /4, since the path difference is l /2. By measuring this distance using a scale, l can be calculated. Assuming..

; in other words, these waves can pass through vacuum They require medium for propagation i.e. these waves cannot pass through vacuum All electromagnetic waves travel with the same velocity Matter waves travel with different velocities The velocity of all electromagnetic waves is equal to that of l..

De-Broglie noted that according to the theory of relativity, the role played by momentum 'P' and the energy 'E' of the particle is done by angular frequency ' w ' and the propagation vector 'k' of a wave. According to Einstein relation E = mc 2 Where 'm' is the mas..

Whenever there is a relative motion between a source of light and the observer, the apparent frequency of light received by the observer is different from the true frequency of light emitted actually from the source of light. If a source of light emits waves of fr..

In 1900, Max Planck presented the results of his famous black body radiation experiments, which showed that light has a dual character, behaving like a particle as well as a wave. He gave the Quantum Theory of Radiation explaining electromagnetic radiation and energy. Its main features were: Ra..
