Question

The approximate speed of sound in air is equal to :

• A. 33.2 $m{s}^{-1}$
• B. 3320 $m{s}^{-1}$
• C. 332 $m{s}^{-1}$
• D. 3.32 $m{s}^{-1}$

Answer 1

The correct option is C 332 $m{s}^{-1}$

Temperature is a condition that affects the speed of the sound.

The approximate speed of sound in air is $332m{s}^{-1}$ at $0{}^{0}C$.
