Why smoke of cigarette has blue appearance?

This is because of Tyndall effect. According to this effect when the light passes through medium containing small particles, it scatters, if the diameter of those particles is less than 25 nano meter the scattered light appears blue. This is the case of tobacco smoke of the cigarette.
