'The voyage in the Beegle'- work of Charles Darwin, after 5 years of
ship voyage.
Gravity ;-----
Sir Isaac Newton discovered the Force of Gravity. His major publication is 'Philosophia Naturalis Principia Mathematica'. Newton's laws of motion published through this book.
Electric Bulb ;-----
Invented by Thomas Alva Edison.
X-Rays(1895) ;-----
Wilhelm Conrad Roentgen, a German physicist invented X-Ray for which he earned the 1st Nobel in 1901. Cathode rays striking heavy metals with high melting point, x-rays are produced.
They're electromagnetic waves produced in Coolidge tubes.
X-ray intensity depends on heating voltage or filament current.
1) Used to detect bone fractures, bullet or stone in the body, treat cancer like diseases.
2) Used in study of crystal structure, detecting pearls in oysters.
In honor of his contributions, International Union of Pure & Applied Chemistry(IUPAC), named element Roentagenium after his name.
Raman Effect ;-----
C V Raman discovered Raman effect.
It is used to study Molecular Energy.
February 28 is celebrated as National Science Day, the very day on which Raman effect was declared.
Infrared Rays ;-----
1) Electromagnetic waves used in breath analyzers to catch people driving under alcohol.
2) Used in airports to detect people suffering from swine flu.
3) Used to treat muscular strain, taking photograph in fog/smoke, in greenhouse to keep plants warm, in weather forecasting through infrared photography, in night vision apparatus.
Ultraviolet Rays ;-----
1) Used in study of molecular structure, in sterilizing surgical instruments, detecting forged documents & fingerprints, in water purification to kill harmful microorganisms.
Radar ;-----
Detect & measure distance & position of clouds, explore metal/oil reserve, outer layer of atmosphere, locate& identify aeroplanes, ships, missiles etc.
Masers ;-----
Detect actual position of the artificial position of the artificial satellites, fighter planes, unwanted missiles etc.
Photoelectric Effect ;-----
Phenomenon of emission of electrons from a metal surface when light of suitable frequency strikes it.
