Because rainbows are seen on the opposite side of the sky from the Sun, rainbows are more visible the closer the Sun is to the horizon. For example, if the Sun is overhead, any possible rainbow appears near an observer's feet, making it hard to see, and involves very few raindrops between the observer's eyes and the ground, making any rainbow ...
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [1]
A 2009 study [109] also suggests deleterious impacts on animals and ecosystems because of perturbation of polarized light or artificial polarization of light (even during the day, because direction of natural polarization of sun light and its reflection is a source of information for a lot of animals).
10.12 Then spoke Joshua to the LORD in the day when the LORD delivered up the Amorites before the children of Israel; and he said in the sight of Israel: 'Sun, stand thou still upon Gibeon; and thou, Moon, in the valley of Aijalon. 10.13 And the sun stood still, and the moon stayed, until the nation had avenged themselves of their enemies.
Mushrooms, molds, and other fungi are not plants, despite similarities in their morphology and lifestyle. The historical classification of fungi as plants is defunct, and although they are still commonly included in botany curricula and textbooks, modern molecular evidence shows that fungi are more closely related to animals than to plants.
“The biggest thing that you need for fire propagation is a source of oxygen,” Tate said. “And with the winds being able to transport so much of the smoke and the burned matter away from the ...
A clear daytime sky, looking toward the zenith. Earth's atmosphere scatters short-wavelength light more efficiently than that of longer wavelengths. Because its wavelengths are shorter, blue light is more strongly scattered than the longer-wavelength lights, red or green.
Height: It is a very large plant and can be 20 feet tall. Dangers: The sap of the plant is highly toxic and can cause sensitivity to UV rays. This can lead to severe blistering and burning from ...
