In loudspeakers sound waves are generated by electromagnetic induction.
Simple harmonic motion can be considered to be the one-dimensional projection of uniform circular motion.
When producing sound, the vocal cords are vibrated by the air flowing out of the lung.

In 1946 a Hungarian scientist was the first person to detect radar echoes from the Moon.
It is a well-known phenomenon that the sound of an approaching sound source is higher than that of a receding one.
Waves play an extremely important role in many areas of our lives.
