Question

The frequency of a tuning fork is 256Hz. The
velocity of sound in air is 344ms-1. The
distance travelled (in metres) by the sound
during the time in which the tuning fork
completes 32 vibrations is​

Answer 1

Answer:

Frequency is given as f=256 Hz

Time period of tuning fork T=

f

1

=

256

1

As T is the time in which tuning fork will complete one vibration.

So, 32 T is the time in which fork will complete 32 vibrations.

∴ Time elapsed during 32 vibration t=32T=32×

256

1

sec

Distance traveled by sound during this time d=Vt =344×

8

⟹ d=43 m
