The dew point is quite literally the temperature at which water in the air will start to condense and form droplets.
It's commonly used by pilots. As you get higher, the temperature drops and eventually you will get to a height where you reach the dew point temperature... this hight varies according to pressure, humidity and overall temperatures, but piecing all the information together, a pilot can work out at what height the air will be at dew point... And this is where clouds start to form. That way, a pilot can avoid any nasty surprises!

Good question and here is the scientific answer you are looking for. If the air were to cool to -1.3C it would be saturated i.e. humidity of 100%. Because the dewpoint is below freezing it is called the frost point water vapor will change directly into frost without condensing into liquid first. Hope this clears things up for you.

This is the temperature that the air needs to be in order to be saturated and have dew form. If it goes lower than this temperature, fog will from.

the air would have to be cooled to that temp (-1.3 C) to become saturated (with water).
