Velocity of sound waves in air is330 m/s.For a particular soundin air ...
Phase difference=2πfeq.of wave/velocity×path difference phase difference=1.6π;velocity=330;path difference=40cm ---->0.4m;freq.of wave=? 1.6π=2π×freq.of wave/330×0.4 frequency of wave=1.6×π×330/0.8×π frequency of wave=528/0.8 so;we get frequency of wave=660Hz...hope u clear...!😊👍

Velocity of sound waves in air is330 m/s.For a particular soundin air ...
To find the frequency of the sound wave, we need to first convert the path difference from centimeters to meters:
40 cm = 0.4 m
Next, we can use the formula for phase difference:
Phase difference = (2π / λ) * path difference
Given that the phase difference is 1.6, we can rearrange the formula to solve for the wavelength:
1.6 = (2π / λ) * 0.4
1.6 = 0.8π / λ
λ = 0.8π / 1.6
λ = 0.5π
Now we can find the frequency using the formula:
Velocity = frequency * wavelength
330 = frequency * 0.5π
frequency = 330 / (0.5π)
frequency ≈ 209.44 Hz
Therefore, the frequency of the sound wave is approximately 209.44 Hz.
40 cm = 0.4 m
Next, we can use the formula for phase difference:
Phase difference = (2π / λ) * path difference
Given that the phase difference is 1.6, we can rearrange the formula to solve for the wavelength:
1.6 = (2π / λ) * 0.4
1.6 = 0.8π / λ
λ = 0.8π / 1.6
λ = 0.5π
Now we can find the frequency using the formula:
Velocity = frequency * wavelength
330 = frequency * 0.5π
frequency = 330 / (0.5π)
frequency ≈ 209.44 Hz
Therefore, the frequency of the sound wave is approximately 209.44 Hz.
