Heya frnd..
Here is your answer..
Step-by-step explanation:
Given,
Frequency, ν = 2 kHz = 2000 Hz
Wavelength, λ = 35 cm = 0.35 m
We know that speed, v of the wave
= wavelength frequency
v = λ ν
= 0.35 m × 2000 Hz = 700 m/s
The time taken by the wave to travel a
distance, d of 1.5 km is
Thus sound will take 2.1 s to travel a
distance of 1.5 km.
