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 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 […]
