Frequency = 2KHZ.
Wave length = 35 Cm
Convert KHZ into Hz.
2KHZ = 2000 Hz.
Convert Cm into m.
35 Cm = 0.35 m.
According to question ..
A sound wave has a frequency of 2KHZ and wavelength 35cm how long it will take to travel 1.5 km.
Formula used => Velocity =
frequency × wavelength .
2000Hz × 0.35 m.
700 m/ s .
The time taken by the wave to travel a distance ,d of 1.5 km is.
t =
FINAL ANSWER = 2.1 S

1.5×1000m
= [tex] \frac{15}{7}..
