Question

During a time-interval of exactly one period of vibration of a tuning fork, the emitted
sound travels a distance
(a) equal to the length of tuning fork
(b) of about 330 m
(c) which decreases with time
(d) of one wavelength in air​

Answer 1

Answer:d

Explanation:

as the time period of one vibration can be anything so we cannot say that specifically what will be the distance travelled.

so option (b) and option (a) are wrong.

distance travelled in stone interval will be same in every given time interval.

so option (c) is also not true.

as we know that in a complete vibration of a tuning fork it will produce a rarefaction and compression wave. and this we know that a compression and rarefaction forms a wavelength.

so distance travelled would undoubtedly be equal to the wavelength of the wave produced.

Hope that helps.
