wave diagrams

. 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 time at a particular ..

You must have noticed that in all the above diagrams the arrows representing the ray of light are perpendicular to the wavefront. According to Huygen, these straight lines are rays of light that are normal to the wave point. Thus the light energy flows along the ra..

Why microwaves are preferred over other waves to beam signals in a particular direction? Microwaves are radio waves with frequencies higher than television signals. The wavelengths of microwaves are of the order of a few millimeters. We know that sound waves spread and..

. They are named as PQRST. The P Wave represents the first upward deflection of the ECG. It takes place when the impulse spreads over the atrial chambers. Its average duration is about 0.1 second. It represents the depolarization of the atrial musculature. The QRS complex is the combined ..

. These bands are called interference fringes. The solid arcs represent the crests and the dotted arcs represent the troughs in the above diagram. When these arcs overlap, the (.) dots represent the maximum intensity i.e., constructive interference, whereas the (x) crosses represent the m..

The tides are formed due to the gravitational force of attraction between the earth, sun and moon. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity. The block diagram given below illustrates the transformation..

Question: Consequences of Nuclear Explosions The detonation of a nuclear bomb over a target such as a populated city causes immense damage. The degree of damage depends upon the distance from the centre of the bomb blast, which is called the hypocenter or ground zero. The closer one is to ..
