Rainbow gravity (or "gravity's rainbow" [1]) is a theory that different wavelengths of light experience different gravity levels and are separated in the same way that a prism splits white light into the rainbow. [2] This phenomenon would be imperceptible in areas of relatively low gravity, such as Earth, but would be significant in areas of ...
Due to the finite wall thickness and the macroscopic character of the artificial raindrop, several subtle differences exist as compared to the natural phenomenon, [88] [89] including slightly changed rainbow angles and a splitting of the rainbow orders.
It takes all the colors of the rainbow for us to see it that way. It happens because of something called the Rayleigh effect, or Rayleigh scattering, named after a British scientist who first ...
An aurora is a natural phenomenon. A natural phenomenon is an observable event which is not man-made. Examples include: sunrise, weather, fog, thunder, tornadoes; biological processes, decomposition, germination; physical processes, wave propagation, erosion; tidal flow, and natural disasters such as electromagnetic pulses, volcanic eruptions ...
A common optical phenomenon involving water droplets is the glory. [23] A glory is an optical phenomenon, appearing much like an iconic Saint's halo about the head of the observer, produced by light backscattered (a combination of diffraction, reflection and refraction) towards its source by a cloud of uniformly sized water droplets. A glory ...
The world Gravity’s Rainbow was born into on February 28, 1973: a post-Kennedy, post-MLK, Vietnam and Nixon era in which cynicism, fatalism, suspicion, and paranoia bloomed. 1973 was the year ...
One common example is the rainbow, when light from the Sun is reflected and refracted by water droplets. Some phenomena, such as the green ray, are so rare they are sometimes thought to be mythical. [2] Others, such as Fata Morganas, are commonplace in favored locations. Other phenomena are simply interesting aspects of optics, or
A semi-artificial Brocken spectre created by standing in front of the headlight of a car, on a foggy night. The "spectre" appears when the sun shines from behind the observer, who is looking down from a ridge or peak into mist or fog. [1] The light projects the observer's shadow through the mist, often in a triangular shape due to perspective. [2]
