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
