The concept required to solve this problem is related to the wavelength.
The wavelength can be defined as the distance between two positive crests of a wave.
The waves are in phase, then the first distance is
![\Delta x_1 = 20cm](https://tex.z-dn.net/?f=%5CDelta%20x_1%20%3D%2020cm)
And out of the phase when
![\Delta x_2 = 30cm](https://tex.z-dn.net/?f=%5CDelta%20x_2%20%3D%2030cm)
Thus the wavelength is
![\Delta x_2-\Delta x_1 = \frac{\lambda}{2}](https://tex.z-dn.net/?f=%5CDelta%20x_2-%5CDelta%20x_1%20%3D%20%5Cfrac%7B%5Clambda%7D%7B2%7D)
Here,
Wavelength
If we rearrange the equation to find it, we will have
![\lambda = 2 (\Delta x_2-\Delta x_1 )](https://tex.z-dn.net/?f=%5Clambda%20%3D%202%20%28%5CDelta%20x_2-%5CDelta%20x_1%20%29)
![\lambda= 2(30-20)](https://tex.z-dn.net/?f=%5Clambda%3D%202%2830-20%29)
![\lambda = 20cm](https://tex.z-dn.net/?f=%5Clambda%20%3D%2020cm)
Therefore the wavelength of the sound is 20cm.
Answer:
It does not affect. The closest nebula is the Orion Nebula at more than 1300 light years from Earth. It is so remote that nothing that happens there can influence the Earth. The only influence is to have beautiful colors and shapes and to let us dream one day to go there and explore them.
