Question

Quizplus · Accepted Answer

A wet-bulb thermometer and a dry-bulb thermometer are both parts of a sling psychrometer, which is used to measure relative humidity in the atmosphere. The wet-bulb temperature is measured by wrapping the bulb of one thermometer with wet fabric and then swirling the psychrometer through the air, allowing moisture to evaporate and cool the wet-bulb. The dry-bulb thermometer measures the actual air temperature. By comparing the two readings, relative humidity can be determined using a chart or formula.
