Web13 mrt. 2024 · When light travels through space from the sun, all of the frequencies of light travel in a straight line. When light hits the atmosphere, however, the photons begin to collide with gas molecules. Red, orange and yellow photons have long wavelengths and can travel right through the gas molecules. Green, blue and purple photons, however, have ... WebAnswer (1 of 8): A very confused question. First of all, LASER. Not LAZER. S means “stimulated”. A laser is basically three things: something that “generates the photons” and something that “excites the electrons”. And a HOLE for that light to come out of. It is not really a good idea to tal...

Until the early modern period, it was not known whether light travelled instantaneously or at a very fast finite speed. The first extant recorded examination of this subject was in ancient Greece. The ancient Greeks, Arabic scholars, and classical European scientists long debated this until Rømer provided the first calculation of the speed of light. Einstein's Theory of Special … WebLight travels 300,000 kilometers per second in a vacuum, but it slows down to 225,000 kilometers per second in water and 200,000 kilometers per second in glass. What Cannot exist in a vacuum? If something happens in a vacuum and you don’t expect it to be connected to other things, it’s a common occurrence. opto ctr

Web7 jul. 2024 · Light traveling through a vacuum moves at exactly 299,792,458 meters (983,571,056 feet) per second. That’s about 186,282 miles per second — a universal constant known in equations and in shorthand as “c,” or the speed of light. Does light lose energy in space? http://scienceline.ucsb.edu/getkey.php?key=307 Web1 dag geleden · The fastest thing in the whole universe is the speed of light in a vacuum (like outer space!), clocking in at a great 2.99 x 10 8 m/s. Light travels in waves, and we call this traveling propagation. Propagation of waves has both a speed and a direction, called the velocity. The velocity of light changes depends on the material it travels through. opto control system
