WebNov 11, 2024 · Moon: It takes about 1.255 seconds for light to get from Earth to the moon. Mars: Mars is about 150x further than the moon — about 40 million miles (54.6 million km) in the closest approach — so it takes 3 minutes to get there from Earth. Sun: The sun is 93 million miles (150 million km) away, meaning it takes 8 minutes to see its light. Web@sst When the wavelength of light enters a medium, it slows down. Therefore the speed is not c anymore. The decrease in velocity is proportional to the decrease in the wavelength, which is how the Energy stays constant in the equation E=hc/l. – Dale Dec 4, 2012 at 5:17

WebDec 10, 2024 · The speed of light only differs when comparing it in two mediums with a different refraction index. With the added changes we can say that the detector with v = v … WebThe speed of light in a vacuum, c, is 3×10 9 m s −1.When light passes through a transparent medium, it passes between the atoms at the speed c.However, each interaction with charged particles in the medium delays the phase of the light, so that its speed within the medium, v, is reduced.The ratio of the speed of light in vacuum to the speed of light in the … http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/refr.html bank btn kebon jeruk
