Question
Sodium lamps are used in foggy conditions because:
Options
A.yellow light is scattered less by the fog particles
B.yellow light is scattered more by the fog particles
C.yellow light is unaffected during its passage through the fog
D.Wavelength of yellow light is the mean of the visible part of the spectrum
Solution
The higher the wavelength the lesser the scattering. yellow light has higherwavelength so it is least likely to be scattered (except red & orange). So this light is visible from long distance ever when there is foggy weather.
