At 20^ C , the speed of sound in water is approximately

Options

  1. A330 ~m / s
  2. B800 ~m / s
  3. C1500 ~m / s
  4. D5000 ~m / s

Correct answer

C. 1500 ~m / s

Step-by-step solution

Sound is a type of longitudinal, mechanical wave. They need a medium to propagate and will not travel through a vacuum. Sound travels at different speed in different media. The speed of sound is determined by the density ( ) and compressibility ( K ) of the medium. According to the World Book Encyclopedia, Chicago: World Book, 1999. 601, "The speed of sound in Distilled Water at 77^ F (25^ C ), 1496 ~m / s , 4908 ft / s " or 1496 ~m / s (1500 ~m / s ) .
