Numerical problems:
A person is listening to a tone of 400 Hz from a distance of 500 m from the source of the sound. What is the time interval between successive compressions from the source?
थोडक्यात उत्तर
उत्तर
Frequency of tone u = 400 Hz.
The time interval between two
successive compressions
from the source = the Time period of the wave.
Time Period, T = `1/"Frequency(υ)"`
T = `1/"400s"^-1"` = 0.0025 s.
The time interval between two successive compressions from source = 0.0025 s.
