Efeito Doppler

Synopsis: This is a virtual laboratory and is divided into two stages: the first time will be on the street and have an observer (human) and a frequency emitting source (ambulance or police car). Thus, students can see how the Doppler effect is present in their daily visual and sound manner. The second stage will take place in the same scenario, but is merely visual, ie only show the motion of the source and the waves of the produced frequency. However, now the emission source is a plane. At this point the student will only handle the speed of the airplane considering three speeds: subsonic, sonic and supersonic, which can range from zero to 680 m / s.
