Q10 of 54 Page 390

Write true of false for the following statements:

Sound produced by a sounding body of frequency 300 Hz covers 34 m in the time the sounding body produces 30 vibrations.

True

Explanation:


Given,


Frequency(f) = 300 Hz


No. of vibration = 30


Distance travelled by sound = 34 m





After 30 vibrations,


Total time taken = No. of vib.×Time period



Distance travelled = speed âtime


Distance = 340×0.1 = 34 m
