What is the Doppler Effect?
The Doppler Effect has to do with a change in frequency and volume. When an object is further away, it has a lower volume and frequency. As the object, say a car, is nearing you; the frequency gets higher and so does the volume. As the object passes by you, the frequency gradually slows down and the volume gets lower. When you hear the Doppler Effect, it's like when you hear a train whistle. It's hard to hear at first, but as it gets closer, it gets louder. When it leaves it dies away. Most would recognize the Doppler Effect as the sound it makes, "Neorm!"
The Doppler effect is observed with visible light and all other electromagnetic waves. The electromagnetic radiation discharged by a moving object also exhibits the Doppler effect. When the distance between the source and receiver of electromagnetic waves is increasing, the frequency of the received wave forms is lower than the frequency of the source wave form. When the distance is decreasing, the frequency of the received wave form will be higher than the source wave form.
