travelling waves amplitude

The measure of the height of a wave or the depth of its trough is called amplitude. Amplitude determines the intensity or brightness of a wave. It is denoted by the letter 'A..

Waves may be considered as disturbances, which originate from some vibrating source and travel outwards as a continuous sequence of alternating up and down movements called crests and troughs respectively...

But mn = mass per unit volume = density ( r ) The transfer of energy per unit time per unit area, perpendicular to the direction of motion of the wave, is called the intensity (I) of the wave. In unit time, the wave will have traveled a distance v. Therefore,..

In this type if modulation, w c and q are kept constant. The amplitude E c of the carrier wave is varied in accordance with the modulating wave..

When the amplitude of high frequency carrier wave is changed in accordance with the intensity of the signal, it is called amplitude modulation. In amplitude modulation, only the amplitude of the carrier wave is changed in accordance with t..

Let two similar waves of amplitudes A 1 and A 2 having same frequency and wavelength travel past a point in a medium, producing individual displacements y 1 and y 2..

Wave motion is the propagation of a disturbance produced in a medium by the repeated periodic motion of the particles of the medium. It is only the energy of the disturbance that moves forward without any mass transfer. In an elastic medium, the frequency and the amplitude..

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) ..

In stationary waves, there are certain points called nodes where the particles are permanently at rest and certain other points called antinodes where the particles vibrate with maximum amplitude. The nodes and antinodes are formed alternately. All the particles of the medi..

Equation for a Progressive Wave - The simplest type of wave is the one in which the particles of the medium are set into simple harmonic vibrations as the wave passes through it. The wave is then called a simple harmonic wave. Consider a particle O ..
