IGCSE Grade 10 Science Speed of sound in air
|
Sound waves travel at a speed of about 340 m/s in air at room temperature The higher the air temperature, the greater the speed of sound
The human hearing range depends on both the pitch of the sound – whether it is high or low – and the loudness of the sound. Pitch is measured in Hertz (Hz) and loudness is measured in decibels (dB).
Sound waves travel at a speed of about 340 m/s in air at room temperature The higher the air temperature, the greater the speed of sound The speed of sound in air varies from 330 – 350 m/s

Rooms having walls less than 17.2 m away from each other, no echo can be heard. here, 169 m is greater than 17.2 m. So an echo will be heard if other conditions are fulfilled.
