Multiple Choice

What unit is used to describe typical aerial droplet sizes?

Explanation:
Droplet sizes used in aerial spraying are described in micrometers (microns). A micron is one millionth of a meter, which matches the tiny scale of droplets that remain suspended and can drift in the air. Nanometers are far too small for spray droplets, while millimeters and centimeters are far too large for aerosol particles. In mosquito control, droplets are typically in the tens of micrometers range, making micrometers the practical unit for describing aerial droplet sizes.
