Speed of light
From Wikipedia, the free encyclopedia
Jump to: navigation, search

"Lightspeed" redirects here. For other uses, see Lightspeed (disambiguation).

The speed of light in a vacuum is an important physical constant denoted by the letter c for constant or the Latin word celeritas meaning "swiftness".

In metric units, c is exactly 299,792,458 metres per second (1,079,252,848.8 km/h). Note that this speed is a definition, not a measurement, since the fundamental SI unit of length, the metre, has been defined since October 21, 1983 in terms of the speed of light: one metre is the distance light travels in a vacuum in 1/299,792,458 of a second. Converted to imperial units, the speed of light is approximately 186,282.397 miles per second, or 670,616,629.384 miles per hour, or almost one foot per nanosecond.

Through any transparent or translucent material medium, like glass or air, it has a lower speed than in a vacuum; the ratio of c to this slower speed is called the refractive index of the medium(the actual speed is not affected, the speed of light is constant, the fact that the light is reflected around inside the glass will make a greater amount of time necessary for it to reach the next point). In an analogous way, the light speed is also affected by changes in gravity. This gives rise to the phenomenon of gravitational lensing, in which large assemblies of matter can refract light from far away sources, so as to produce multiple images and similar optical distortions.

PP TALK:

4 pictures to have this image.
Experimented on the blending modes.


CALLING ALL PHIL TREKKIES:
We will have an EB on the NOV 6 at Giligans, Glorieta, Makati City 7 PM. Kindly check this thread:

The first link which i posted was moved. Silly me. Lol. But this is the new link. See you guys there!

Hi Emmanuel,
The physics Note is too technical for me. But the image is delightful. I am a big fan of slow shutter speed. Prolonging the exposure almost always produce interesting shots, just like here. Best wishes. Danilo

Pare, ayusin mo yang date mo ng EB. dapat Nov 6, hindi nov 26! Ikaw talaga, sa bilis mo kasing mag motorsiklo nalilito ka na tuloy. hehehe!

Nice panning shot here!

TFS!

hahaha! oo nga naman dre! napa lightspeed ata date mo eh hahaha! :D wow! nag prpractice na ng blending :D Nice work dre!

Hi Emmanuel,
Great idea and result !
Interesting note.
