Question

A sound wave has a frequency of 2KHz and wave length 35 cm how long will it take totravel 1.5km​

Answer 1

Answer:

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.
