The Doppler Effect is an effect seen in light and sound waves as they push toward or away from a spectator. One basic cause of the Doppler effect is the sound of a vehicle horn. Picture an individual remaining on a traffic intersection. A vehicle draws near, blowing its horn. As the vehicle keeps pushing toward the individual, the pitch of the horn seems to expand; its sound goes increasingly elevated. As the vehicle passes the onlooker, in any case, the effect is switched. The pitch of the vehicle horn becomes lower and lower. Everything waves can be characterized by two related properties: their frequency and recurrence. Frequency is the separation between two adjoining (close to one another) and indistinguishable pieces of the wave, for example, between two wave peaks (tops). Recurrence is the number of wave peaks that pass a given point for every second. For reference, the frequency of noticeable light is around 400 to 700 nanometers (billionths of a meter), and its recurrence i
