relative frequency

Wave velocity is defined as the distance traveled by the wave in one second. Or Wave velocity = Wavelength frequency..

It is that characteristic of a musical sound which enables us to distinguish between the sounds produced by two different musical instruments or two different persons although their pitch and loudness may be same. It is because of this characteristic that we are able to recognize the voice of a kn..

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 ligh..

The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles, then it should be possible for matter, which consists of particle..

Question: Define the terms velocity and wavelength applied to sound wave and state the relation between velocity, frequency and wavelength. Answer: The distance traveled by a wave in one second is its velocity. The distance traveled by the wave when it completes one ..

Particle Nature of Light - According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron may escape the surface. If we user a low ..

Let a stationary observer on a platform listen to the sound emitted by the whistle of an incoming train. As the train approaches the platform, an increase in the pitch of the sound will be observed. As the engine moves away from him, there will be a decrease in the pitch of the sound. The same effe..

A chromosome map is a graphic representation of a linkage group in the form of a line which shows by points the sequence of the genes and the relative distance between the genes it contains. A chromosomes map is also called a linkage map or genetic map. Since the frequency of cr..
