What is the principle behind Doppler velocimetry working?
What is the principle behind Doppler velocimetry working? Explanation: Doppler velocimetry works on the principle of frequency measurement of fiber optic sensor. The moving red blood cells scatter the light and produce a Doppler frequency shift because of their movement. In this method, light from a laser, normally helium/neon, is sent via a fibre onto […]
What are dislocations in crystals?
What are dislocations in crystals? A dislocation is a linear crystallographic defect or irregularity within a crystal structure which contains an abrupt change in the arrangement of atoms. The crystalline order is restored on either side of a dislocation but the atoms on one side have moved or slipped. How dislocations can be introduced into […]

What is gravity short answer?
What is gravity short answer? The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes […]

Why are metals good conductors of heat and electricity Why does the ability of a metal to conduct electricity decrease with increasing temperature?
Why are metals good conductors of heat and electricity Why does the ability of a metal to conduct electricity decrease with increasing temperature? Metals are good conductors of heat and electricity because the delocalized electrons are mobile. As the temperature increases, electrical conductivity decreases because the metal atoms vibrate more, causing them to collide more […]
