Help fast I want the correct answer please does spectral diffusion cause light to scatter ​
LiRa [457]

Answer: No

Explanation:

Whenever light travelling on a straight line encounters obstruction, it diffracts and scatter.

Scattering of light occurs when light passes through a rough path or a diffused surface.

But in case of spectral diffusion, which is the fluctuation in spectroscopy as a result of time dependent frequency shifts.

Spectral diffusion occurs in particular molecules initiated by excessive excitation energy.

Fluctuation in frequency does not mean diffraction of light or particles

Therefore, spectral diffusion does not cause light to scatter.
