How is wet bulb temperature measured?

Wet bulb temperature is determined through a method that involves using a thermometer with a cloth that is kept moist around its bulb. This approach takes advantage of the cooling effect of evaporation. When the cloth is wet, water from it evaporates, which decreases the temperature around the bulb of the thermometer. The wet bulb temperature reflects both the moisture in the air and the cooling effect of evaporation, providing valuable information about humidity levels and comfort conditions.

The other methods mentioned would not provide an accurate measurement of wet bulb temperature. For example, measuring with just a glass thermometer would only indicate the dry bulb temperature, which does not account for humidity. Using an electronic thermometer or submerging a thermometer in water would not accurately represent conditions in the air since these methods do not involve the process of evaporation that is essential for determining the wet bulb temperature.
