WHAT IS THE DISTANE TRAVELLED BY SOUND IN AIR WHEN A TUNING FORK OF FREQUENCY 256HZ COMPLETES 25 VIBRATIONS? (THE SPEED OF SOUND IN AIR IS 343MS-I)
problem


For a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given period of time.

Distance traveled = Speed  X  Time period
 Time period        = 1/256
                           =3.9062x10-3

Distance traveled= 343 * 3.9062x10-3
                          = 1.339m
