Question

Speed of sound in air near room temperature is approximately:

• A. \( 3.4 \times 10^2\ \text{m/s} \)
• B. 34 m/s
• C. 34 km/s
• D. 3.4 km/s

Hint:

Standard speed of sound in air at room temperature is around 343 m/s.

Answer 1

The Correct Option is A

At room temperature (around 20–25°C), the speed of sound in air is approximately 340 m/s, which is equal to \( 3.4 \times 10^2\ \text{m/s} \).
