Consider the thermometers shown What is true about the dew point under these conditions?

The dew point is the temperature at which air becomes saturated with moisture, leading to condensation. In the context of thermometers, if one reads the wet-bulb temperature, the dew point can be estimated based on the difference between the wet and dry bulb readings. A smaller difference indicates a higher dew point, while a larger difference suggests a lower dew point. Thus, the dew point reflects the moisture content in the air under the given conditions.
