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 6: the factors affecting sound propagation
There are three factors, which affect the sound propagation’s behavior such as the relationship of the pressure and density of the medium, the medium motion and the medium’s viscosity.
Facts about Light and Sound Waves 7: the refracted sound
The sound is refracted when the constant physical properties are not available in the medium.
Facts about Light and Sound Waves 8: the speed of light
Can you count the speed of light in a vacuum? It is 186,282 mps or 299,792,458 meter per second. Many physicists tried to define the speed of light throughout the history. In 17th century, Galileo tried to measure the speed of light.
