Three mutually perpendicular laser radiation three light λ = 500nm Three light green?
Three of the laser beam emitted 500nm = Λ perpendicular to each other, three three green lights. There's a flying range of velocities Ships with a lot of space. Each ship's crew, all three of the beam Wavelength is measured and reported by the shortest wavelength of the three bases measurered. Which the longest wavelength reported? Photons of energy 1 = C and E = P, Assume that the momentum is equal. Vector of the photon momentum - Is the energy of [Io, par, 0, 0] [is it, 0, wave, 0] [is it, 0 0, port] 3Eo their total energy is [briefly summarize all three Momentum wave, wave, wave], and the mass invarinant ² = (3Eo) ² - ² Four - Four ² - ² = 6Eo referenece. ² which is invariant in a frame so large wave enegy frame or at least some of the photons energetic √ (6Eo ²) / 3 = √ (2 / 3) twenty-five Answer: 500nm √ (3 / 2) = 612.4nm
Tricky. Let A short cover letter λ 'is the right direction in him) from the spacecraft at speeds Know (i measure up to speed on eopjyo max. Shortest rate for Like) the longest / λ is the speed can be (in the hotel * = V ',' λ λ - but, going in different directions. This The angle of the ship is heading for the top three are available in all beacons. In other words, if 0,0,1 and 0,1,0 were beacons in the 1,0,0, and the spacecraft -1, -1, title Direction can be -1. This means that its signal to a particular observation The speed with no respect *) is [* a, modify the edit formula Below] λ '= λ + sqrt (1 / 3 (λ - λ'), I avoid the possibility of relativity Because most of the commands will be a few seconds. * Precise editing, I think this is) 3 sqrt (1 / correction, "" element expansion. The three-dimensional Math is a little rusty.

Spider-Man musical looks to snare masses
New York -- Robin Buckwalter is fully aware that a Broadway musical about Spider-Man will be opening soon. So far, though, he hasn't felt a buzz of anticipation about it where he works.
