Dew and frost are actually the same phenomenon, except that dew occurs when the air temperature is above freezing while frost occurs when it is below. Both are condensation that occurs when moisture held in the air is cooled to a point that the air can no longer support it.
True frost occurs when the temperature is low enough for the water vapor in the air to sublimate, or go from a gaseous state to a solid without first becoming a liquid, directly onto objects in the environment. Liquid accumulation that later freezes is not frost, but frozen rain or dew.

hi there
dew-Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation. As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets.
frost-Frost is the coating or deposit of ice that may form in humid air in cold conditions, usually overnight. In temperate climates, it most commonly appears as fragile white crystals or frozen dew drops near the ground, but in cold climates, it occurs in a greater variety of forms.
