The International Isle of Man TT is a crazy motorcycle race. I mean—it's seriously ludicrous. They ride on public roads (yes, they are closed to normal traffic) such that you get these videos of bikes ...

The dual Doppler effect, in the simultaneous occurrence of both normal and inverse Doppler effect in one moving two-dimensional wedge-type photonic crystal, is proposed. An improved finite-different ...

The Doppler shift of sound or light waves from a moving source is familiar to physicists and non-physicists alike. Now, researchers in China and Australia have seen the more exotic inverse Doppler ...

Sitting on the beach at Gecko Island one afternoon, A man finds himself beneath the flight path of the airplanes leaving East Blue Airport. a) What frequency will the man hear as a jet, whose engines ...

Vortex light carries orbital angular momentum (OAM) characterized by exp(ilθ), where θ is the angular coordinate and l is the topological charge (TC) 1. OAM beams have been widely used in a variety of ...

Blackmore's lidar system can detect the velocity of pedestrians and vehicles: objects moving away from the vehicle are in yellow or red, those moving toward it appear blue. This morning I got a ...

So long as skiing and a trombone is involved, there is no such thing as a dull science lesson. For all of us who fell asleep during science class (I see you), the Doppler effect is the change in ...

Radar is quite spectacular in telling us exactly where rain is falling by pinging precipitation with radio waves! Our weather radar can determine more than just a storm’s location, but its movement as ...

On today’s episode of “For Science!” we invite a very special guest to the lab, 9 & 10 chief meteorologist Michael Stevens to discuss the often misunderstood concept of Doppler. Many believe that the ...
