Download Solution PDFThe correct answer is 332 mtr/sec.
Key Points
- Speed of sound
- The speed of sound is the distance traveled in a given amount of time by sound waves.
- The speed of sound given as 343 meters per second is observed under a certain set of conditions, specifically, through dry air at 20°C.
- Sound speeds vary with the temperature of the air, humidity, and even the consistency of the air.
- Sound has a slower speed at lower temperatures for a given medium.
- The particles in the medium travel more slowly at a lower temperature, so it takes longer to transfer the energy of the sound waves.
- The speed of sound decreases by 0.6 m/s for every 1 degree Celsius that the temperature decreases.
- At 0 degrees Celsius, the speed of sound is around 331.5 m/s. Hence, Option 2 is correct.
- For each degree-Celsius temperature rise, the speed of sound rises by 0.6 meters per second (m/s).
