Physicist Trivia! Red Shifts! Rock ON!?
139385
Since the wavelength of green light is 530nm and  red light is 630nm (I'm generalizing),\nv = 0.17c = 0.17 × (3 × <10 to the 5th power> ) × (60 × 60) = 185 × <10 to the 6th power> kph.\nSo unless the fine is a percentage of one cent per mile per hour over the speed limit, it's gonna be steep.

good question....its kind of complicated but basically, one type of Red Shift is similar to the doppler effect for sound. When an ambulance screams towards you the siren gets noticable higher pitched, then when it races away the pitch drops. This is because the sound waves are traveling at a fixed speed  toward your ears, but the fast movement of the ambulance is changing the frequency, or the rate at which those waves hit you. it is essentially smushing more of the sound waves together as it approaches you and stretching them out as it moves away. This same principle applies to light and all electromagnetic waves. \n\nThe other type of red shift include cosmological redshit, and gravitational or (relativistic red shift). \n\nCosmological red shift can occur as space it self expands, this expansion of space expands the actual photons and inturn drops the frequency of the light towards red. \n\nGravitational Red Shift can occur when ever light passed through a gravitational field. Gravity imposses a time dilation effect on anyting in the field and so photons are also subject to this. The result is the drop in frequency towards red. \n\n(it is also important to note that the red shift also applies to all electro magnetic waves visible or not, and in cases where the light would be infra red or already at a lower frequency than red, a red shift would actually shift that wave further away from red.)

The red shift depends on the relative speeds of the source and the detector. It is simply an example of the Doppler shift, which occurs in light whenever there are such differences in velocities.\n\nIt is not true that everything a certain distance away will be moving at the same speed. On top of the expansion of space, there is the peculiar motion of the object itself. So, for example, the Andromeda spiral galaxy is actually moving *closer* to us (i.e. has a blue shift)! The point is that it is close enough that the velocity of expansion is overwhelmed by the particular velocity of that Galaxy. In fact, one of the hard things about estimating Hubble's constant is exactly trying to deal with these peculiar motions.\n\nSo, it is the velocity that determines the red shift, not the distance alone. As you go further out, the velocity of expansion is larger and so the peculiar motions aren't as relevant.

Everyone will answer a yahoo question at the same time causing an irregularity in time/space! Ohhh the Humanity!!!!!

Red! Wait, blue! Pick? Yellow! One of them!!!!!

It certainly sounds like something Bohr would have said to Einstein.  Great Quote!

Dear Madame,\n\nYou could try testing wave-particle duality nature of photons, and report on how the theory corresponds with Schodiger's findings in the early 20th century. \n\nAnyone can put a light bulb in a potato. Also, the above response about commercials is about as unscientific as you can get. I don't trust emus.\n\nPianoguy

Good answer Azreal! Scientists in Australia have actually transported light matter across the laboratory in the last year though....hey its a start!

electron does not orbit the nuleus. this idea was dismissed long back. in fact they spin in their place in either clockwise or anticlockwise direction. \n\noption (c) is correct

So is this sequence based purely on a mathematical function?\n\nOkay, so there's a 52 in there, could this sequence somehow relate to the calendar?\n\nWhat sort of scientist? I'm a computer scientist and nothing's glaringly obvious about those numbers.\n\n** GOT IT *** 68! Er or Erbium, the sequence spells out Brainteaser based on the atomic weights of B, Ra, In, Te, As, and Er.

Yes I work for the institute of color technologies. We need to figure out everyones favortie color in the entire universe.(including aliens) can you help?

Universe is not exactly rotating or spinning... it is said to be constantly expanding... and sorry i don't know about the big band

You want confusion?  Read the website on invariantology-that is the wackiest thing I have read all month!  Hilarious!

Ready?\n\nIn 1900 two theoretical Physicists, Rayleigh and Jeans were working on Black body radiation. A black body is something that re-emits all the radiation it absorbs. They tried to calculate the spectrum of the radiation coming out of a  container who's walls are all black. The frequencies should have been the same, but instead they were yucho. The high frequencies were favored despite theory. "untraviolet catastrophe".\n\nA year later Max Plank figured out that Rayleigh and Jeans assumption that the energy seeped in and out of the box in a perfectly continuous way was Wack.\n\nPlank said the energy moved in descrete packets he called quanta, \n\n"Electromagnetic radiation oscillation v times a second turns out to be made up of a whole number of packets of energy, each amount hv where h is Planck's constant." \n\n"The value of hi is 6.63 x 10 -34 joule-seconds"\n\nHappy mom's day\n\n(love this sh*t)
