ICSE Class 9 Physics
Question 18 of 19
Propagation of Sound Waves — Question 14
Back to all questionsThe speed of sound is directly proportional to the square root of temperature of the medium. It increases by about 0.61 m s-1 (or 61 cm per second) for each 1°C rise in temperature (provided that the rise in temperature is not very large).
i.e.,
Vt = V0 + 0.61t
