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 $330m$
• C. which decrease with time
• D. of one wavelength in air

Answer 1

The correct option is D

of one wavelength in air

The explanation for the correct option

1. We know that a complete vibration of a tuning fork produces a rarefaction and compression wave which forms the wavelength.
2. The distance traveled will be equal to the wavelength of the produced wave.
3. Therefore, option (d) of one wavelength in air is the correct answer
