Sentence examples for using the doppler Effect from inspiring English sources
Measurement of wind speeds can be obtained by photogrammetry (measurements from photographs) and through remote sensing techniques using the Doppler effect.
Radial velocities, measured along the line of sight spectroscopically using the Doppler effect, are not known for all of the recognized stars near the Sun.
To follow the ball, including measuring its spin using the Doppler effect (which causes the radar beam's frequency to rise when it bounces off part of the ball that is spinning towards the detector, and fall when it returns from part that is spinning away), the MLB therefore turned to TrackMan, a Danish radar firm.
Using the Doppler Effect the vibration response between the used blades and a new blade was compared.
By bouncing radar pulses off a near-Earth object and using the Doppler effect induced by its rotation, they can make a picture of sorts.
The hydrodynamic diameter of the solubilized QDs, QD-encoded microparticles coated with polymer shells, and QD-encoded polyelectrolyte microcapsules were determined by the dynamic light scattering method; the surface charge was estimated from their electrophoretic mobility using the Doppler effect by means of a Zetasizer NanoZS (Malvern, UK).
That requires a whole other technique called radial velocity, which uses the Doppler effect to measure the little wobbles in the star caused by the planet's gravitational tug.
We astronomers measure the expansion of the universe using the same Doppler effect that meteorologists use to measure winds on earth.
It consists in precise measuring creep rates at a constant low stress as a function of temperature, using a laser interferometer based on the Doppler effect.
The Doppler effect is used in studying the motion of stars and to search for double stars and is an integral part of modern theories of the universe.
It inherits the advantages of the wave superposition approach in the acoustic computation, and in which a method of moving simple sources is used to eliminate the influence of the Doppler effect.
