WebIn a nutshell: The color we percieve an object to have, is the light that was reflected by that object. For example, a (yellow) banana is reflecting light of approximately 580 nm wavelength. It absorbs the rest (or at least the rest of the visible wavelengths). So the color we see is the light that is reflected. WebApr 27, 2013 · The speed of light is constant, or so textbooks say.

WebI considered the ISS speed v as 8000 m/s or 0.00002667c (c is the speed of light). Then I calculated the epsilon factor as epsilon = sqrt ( 1 – v 2 / c 2 ) = 0.9999999996443555 Finally I applied the epsilon factor to the ISS orbit time (3013 days * epsilon) and found out that the resulting difference is 0.0925 seconds. fallout 4 how many vaults are there
