Statue of young Benjamin Franklin with kite - by Carl Rohl-Smith - 1893. The painting is an example of a history painting, but as West had done in the past with works such as in his 1770 The Death of General Wolfe, he strays from the truth and embellishes many elements for added dramatic effect. Franklin was in his forties and with his son when ...
But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering. But that same phenomenon can also sometimes make skies ...
Whether or not you've seen them in Alaska or Greenland, the spectacular aurora borealis — or, the northern lights — are a mystical, fascinating sight.
A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. [2] A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. [3]
The recorded light pattern is a diffraction grating, which is a structure with a repeating pattern. A simple example is a metal plate with slits cut at regular intervals. A light wave that is incident on a grating is split into several waves; the direction of these diffracted waves is determined by the grating spacing and the wavelength of the ...
Purple and blue are related to nitrogen, with purple lights appearing higher than 60 miles above the ground while blue hues glow below this threshold. Green, red and purple aurora over Mefjord in ...
