Spectral lines provide information about composition and speed of astronomical objects. Spectral lines are gaps in the ordinarily continuous frequency distribution in light. They result when […]
Langer’s lines are areas of tension in the skin that can affect wound healing and scar appearance. Austrian anatomist Karl Langer mapped these lines in the 19th century, noting that they can vary between individuals and locations. Surgeons and forensic pathologists use this knowledge to make incisions and evaluate wounds. Langer’s lines are areas of […]
Topographic maps use contour lines to show elevation and surface shape. Index contours are labeled with increasing numbers, with lighter lines in between representing smaller increments. Contour intervals allow for numerical elevation determination. Contour lines can be measured in different units. They also show surface definition, such as the shape of an island or mountain. […]
