Question
At a particular temperature, the speed of sound in a medium was found to be 450 m/s. The speed of sound in that medium will be _____ if the temperature of the medium is decreased?
- > 450 m/s
- < 450 m/s
- = 450 m/s
- Any of the above
Hint:
When the speed of sound in a medium with a high temperature is 450 m/s, the decrease in the temperature causes a decrease in the speed of sound that will be > 450 m/s.
The correct answer is: < 450 m/s
- The temperature of a medium is directly proportional to the speed of sound in the medium.
- The speed of sound increases when the temperature of a medium increases.
- The speed of sound will decrease with respect to the decrease in the temperature of the medium.
- The speed of a sound in a high-temperature medium with 450 m/s, will decrease when the temperature decreases.
