Answer 2

If the wavelength of the light is halved then the scattering gets doubled. This is also called as Rayleigh scattering.

Explanation:

• Rayleigh scattering is inversely proportional to the fourth power of wavelength.
• When the particles scattering are smaller than the wavelength of light, then this phenomenon is called Rayleigh scattering.
• It says that the light with a shorter wavelength will scatter more than the light with larger wavelength.
• For example: Violet and blue light will scatter more because it has shorter wavelength.
• On the other hand, red and yellow light scatter less.
