The correct answer is False.

Rayleigh scattering is inversely proportional to the fourth power of the wavelength, so operating at the smallest possible wavelengths will actually increase the amount of scattering.

Rayleigh scattering is a scattering phenomenon in which electromagnetic radiation (of which light is a form) is scattered by particles of a much smaller wavelength. Sunlight is scattered by the tiny molecules of air in Earth’s atmosphere, which is why we see a blue sky most of the time.

The amount of scattering is inversely proportional to the fourth power of the wavelength, which means that shorter wavelengths are scattered more than longer wavelengths. This is why we see a blue sky during the day, but a red sky at sunrise and sunset. The blue light is scattered away from our line of sight, while the red light is able to reach our eyes.

If we were to operate at the smallest possible wavelengths, which would be in the ultraviolet range, we would see even more scattering. This is why it is important to wear sunscreen when you are outside, as the ultraviolet radiation can damage your skin.
