As a Shadow is always present on the opposite side, a rain shadow is also present on the opposite side of the rain. A rain shadow region is the leeward side which is opposite to the windward side.What Happens?The wind over a water body like sea or river is usually cooler than the wind on the land. The cooler wind is denser containing a good amount of water molecules and hence is present at a lower level, while the warmer wind is lighter and raises up. The wind over the water bodies sometimes travels over the land carrying water molecules ... Read More

LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. The LASER action was first proposed by Einstein.Applications of a LASERA LASER can be used in many fields. Some of its usages are given here.Used In Welding and Melting: The laser beam welding is mainly used for joining components using high welding speeds and low thermal distortion.Used In Holography: The reason that a hologram cannot be made without a LASER source is that coherence length for laser source can be very high due to which sustained interference pattern will be recorded on a hologram. This suggests the indispensable ... Read More

Holography is a newer photographic technique. In conventional photography, a camera focuses the light reflected from an illuminated three-dimensional object and negative is made initially. Using the negative, a positive print is developed later. This positive print is the only two-dimensional view of a three-dimensional object.Founder of HolographyBased on this, Dennis Gabor developed a novel photographic technique using interferometry. This technique is known as Holography, Holo means complete and Graphy means writing.Holography Vs PhotographyPattern Difference: Hologram produced by Holography is a positive pattern while conventional photography, a negative pattern is produced on the film.The Difference In Dimensions: Photography is the ...
