Which of these best summarises why fine atmospheric particles preferentially scatter blue light over red light? shorter wavelengths (blue) than longer wavelengths (red)

Question
Which of these best summarises why fine atmospheric particles preferentially scatter blue light over red light? shorter wavelengths (blue) than longer wavelengths (red)
Blue light travels faster than red light in the atmosphere
Fine particles smaller than the wavelength of light are more effective at scattering
Red light has no wavelength at all
Blue light is heavier than red light
Answer
Fine particles smaller than the wavelength of light are more effective at scattering
Detailed Explanation
The chapter explains that particles smaller than the wavelength of visible light scatter shorter (blue) wavelengths more effectively than longer (red) wavelengths.
