Answer:
Path difference = 24 cm
Explanation:
Given:
- Phase difference = 120°
- Velocity of the wave = 360 m/s
- Frequency = 500 hz
To Find:
- The path difference
Solution:
First finding the wavelength of the wave.
We know that,
where λ is the wavelength, v is the velocity and ν is the frequency of the given wave.
Substituting the data we get,
Hence the wavelength of the given wave is 0.72 m.
Now finding the path difference between the two points which is given by the equation,
where φ = phase difference, λ is the wavelength of the wave
Substituting the data,
Hence the path difference of the waves is 24 cm.
