Facts about Light and Sound Waves tell the readers about two interesting topics in physics. The air and water are considered as the two common media, which transmit the sound waves. The frequency of sound waves, which can be heard by human beings, is at the range of 20 Hz to 20 KHz. The hearing range is varied among animals. Let us check other interesting facts about light and sound waves below:

## Facts about Light and Sound Waves 1: the acoustics
