A wet bulb thermometer, simply has the sensitive bulb, dampened with water.
A small muslin bag with wick attached, is placed over the bulb. The wick is placed in a small container of water, which must be periodically topped up.
The water around the bulb evaporates, giving a cooling effect. As the water evaporates, more is drawn via the wick from the reservoir.
The amount of evaporation, will depend on the water saturation already in the atmosphere. By comparing the temperature with a normal thermometer and reading the results in a table, the dew point can be found.

What equipment would you need to perform an experiment that measures relative humidity?
wet bulb and dry bulb temps.
Is The wet bulb thermometer reading is always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
Is the wet bulb thermometer reading always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.

No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
What is the effect of humidification on wet bulb temperature?
wet bulb temparature will increases

What does a wet bulb and a dry bulb measure?
A wet bulb measures the temperature after water evaporation allows to cool and a dry bulb measures air temperature.
