Nounphenomena pl.
From Wiktionary under the GNU Free Documentation License. A phenomenon (from Greek φαινόμενoν), plural phenomena, is any observable occurrence. In popular usage, a phenomenon often refers to an extraordinary event. In scientific usage, a phenomenon is any event that is observable, however commonplace it might be, even if it requires the use of instrumentation to observe it. For example, in physics, a phenomenon may be a feature of matter, energy, or spacetime, such as Isaac Newton's observations of the moon's orbit and of gravity, or Galileo Galilei's observations of the motion of a pendulum. Use in gemologyIn gemology a phenomenon is an unusual optical effect that is displayed by a gem. Play-of-color, labradorescence, iridescence, adularescence, chatoyancy, asterism, aventurescence, lustre and color change are all phenomena of this type. From Wikipedia under the

Asked by ER34 - Mon Jun 28 15:06:47 2010 - - 3 Answers - 0 Comments Which optical phenomena causes the sky to appear blue? Q. Which type of optical phenomena would best explain why the sky is blue? Reflection, Refraction, Diffraction or Interference? Why? I think it might be refraction. I don't want to hear about Rayleigh scattering I already know about that. Asked by master_shmegal - Thu Jul 30 17:46:17 2009 - - 4 Answers - 0 Comments A. It's not refraction. It's largely Rayleigh scattering, sorry, with Mie scattering contributing. From : "Rayleigh scattering of sunlight in clear atmosphere is the main reason why the sky is blue: Rayleigh and cloud-mediated scattering contribute to diffuse light (direct light being sunrays)." From : "Scattering and absorption are major causes of the attenuation of radiation by the atmosphere. Scattering varies as a function of the ratio of the particle diameter to the wavelength of the radiation. When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength. At larger values of the ratio of particle diameter to wavelength, the… [cont.] Answered by Argent - Thu Jul 30 17:57:55 2009 Are the phases of the moon a periodic phenomena?
Q. Are the phases of the moon a periodic phenomena? Explain. Asked by thomasgraham880 - Sun Dec 3 00:45:30 2006 - - 2 Answers - 0 Comments A. Yes, in fact there are 8 common phases, listed below. 1 Full=Moon 2 Gibbous (between Full and Half) 3 Half-Moon (look like half a circle) 4 Crescent (between Half and Dark) 5 New (Dark) 6 Crescent (between Dark and Half) 7 Half-Moon 8 Gibbous (between Half and Full) Full-Moon If we were to write this as a sequence we would get: F ---> G ---> H ---> C ---> N ---> C ---> H ---> G ---> F And this repeats over and over! For fun draw 8 circles next to each other and shade in each one correctly to match the sequence written above!
