Dew on grass. Coloured environmental scanning electron micrograph (ESEM) of dew (blue) on a blade of grass. Dew is water vapour that has condensed from the air. As air cools at night it can hold less water vapour,so any excess water vapour condenses. Unlike a conventional scanning electron microscope (SEM),samples can be examined in an environmental SEM without being desiccated or coated in gold. Magnification unknown | |
