calculations on wave involving phase difference

When a wave passes through a medium, the particles of the medium vibrate about their respective mean positions in the same manner, but reach the corresponding positions in their paths at different instants of time. These relative positions represent the phase of the m..

Photochemical and Biosynthetic Phases - Light Phase consists of photochemical reactions which are carried out by two different photo systems, PS-I and PS-II. In the thylakoids, chlorophyll and other molecules are packed into units called photo systems. Each photosystem..

Comparison between Progressive Waves and Stationary Waves - Progressive waves Stationary waves The disturbance produced in the medium travels onward, it being handed over from one particle to the next. Each particle executes the same type of vibration as the ..

Progressive waves Stationary waves The disturbance produced in the medium travels onward, it being handed over from one particle to the next. Each particle executes the same type of vibration as the preceding one, though not at the same time. There is no onward moti..

. The experiment to observe such a phenomenon was first done by a doctor, Thomas young. Thomas YoungThe above phenomenon was difficult to observe as the two waves had to be coherent i.e., the two waves should have a constant phase difference with respect to t..

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 of osci..

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 medium except ..

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 in the medium. The displacement at any insta..

>, which therefore begins to vibrate. After a time , P 3 picks up the vibration. In this way, after a time T, the disturbance will have just reached P 9 . At this stage, P 1 and P 9 will be in the same state of vibration or will be in phase. The trough (valley) and the crest (hump) togeth..

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 . Then, , Where f is the phase difference between the waves at the point under co..
