takes place only in the presence of sunlight. In this reaction, the light energy from the sun is absorbed by the photosynthetic pigments and is used to break down the water molecules. This is called the photolysis ('photo' is light and 'lysis' refers to break down) of water. ..

S is a narrow slit illuminated by a monochromatic source of light. Two fine slits A and B are placed symmetrically parallel to S. When a screen is placed at a large distance from A and B, alternate bright and dark bands parallel to the slits appear on the scr..

Wave trains for laser light may be several hundred kilometers long. Interference fringes can be set up by combining two beams that have followed separate paths whose lengths differ by as much as this amount. The corresponding coherence length for light from a tungsten..

Let us consider the case of electromagnetic radiation in an ionised medium. Suppose we increase/decrease the amplitude of an electromagnetic wave passing through an ionised gas. These modulations of the electromagnetic wave could contain coded information (Morse code for example). One would expect..
