The speed of sound and the speed of light are two fundamentally different quantities with significantly different values. The speed of sound refers to the velocity at which sound waves propagate through a medium, such as air, water, or solids. The speed of sound is dependent on the properties of the medium, such as density and elasticity. In dry air at sea level and at a temperature of about 20 degrees Celsius, the speed of sound is approximately 343 meters per second or 1,125 feet per second. #
