Frost-covered trees and Glastonbury Tor

Frost-covered trees and Glastonbury Tor. Hoar frost covering three willow (Salix sp.) trees in a field on a farm. St Michael's Tower can be seen on the summit of Glastonbury Tor in the background. Hoar frost results when heat is lost through radiation into the open sky on cold clear nights, causing objects to become colder than the surrounding air. This temperature difference causes the water in the warmer air to condense on the colder objects and then freeze into small ice crystals. Photographed in Somerset, England, UK, in December

H-He-Hg emission spectra C017/7260

H-He-Hg emission spectra. Graphical representation of the emission spectra lines for the elements hydrogen (H), helium (He) and mercury (Hg). The vertical bars represent the colour and wavelength (in nanometres) of the lines seen in spectra from light emitted by excitation of these elements in gaseous form. Studying the peaks in emission spectra from unknown materials enables the identification of elements present in those materials, a technique known as emission spectroscopy
