Physics Voyager hello students,

i conduct tuition classes for a level and o level students. i teach physics and mathematics. as a specialist in physics i conduct class

Doppler Effect is a very interesting and useful phenomenon in physics which is described as the frequency shift between the transmission and receive of a mechanical or electromagnetic wave due to the relative motion of a source and a detector. this effect is very much applicable in vehicle speed detection. previously a radar signal was used as the electromagnetic wave of which the frequency reflected from a moving object is observed to be little shifted from its original signal frequency (pulse).

nowadays a laser radiation is used for speed detection. laser is very much powerful than usual radar signals and laser can be propagated for a very long distance with extremely small loss as the laser light can easily be targeted in a straight line without splitting.
