A photon has an energy of 1.9 meV (milli electron Volt). What is the wavelength of this photon, expressed in micrometers? Keep four significant digits.
And the answer is NOT 6.543
Energy produced in the center of the Sun has a hard time finding its way out. We can estimate roughly how long it takes an average photon to get out by looking at the motion in one dimension only. On average, a photon goes about 1 cm between collisions with hydrogen nuclei or electrons and undergoes about 108 such collisions per second. (Use the hints in problem 29 if necessary. ) (a) What is the average distance traveled in any dimension per step? (b) What is the standard deviation about this value? (c) The radius of the Sun is about 7.0 x10³ m. About how many steps must a photon take before having a 32% chance of being outside the Sun in this dimension? (d) To how many years does this number of steps correspond? (1 year = 3.17 x 107 seconds).
Gamma rays (?-rays) are high-energy photons. In a certain nuclear reaction, a ?-ray of energy 0.836 MeV (million electronvolts) is produced. Compute the frequency of such a photon.

I know it's not because of quantum mechanics and uncertainty like some people say, because particals at their lowest zero-point will have a temperature of exactly 0 K, even though they're still experiencing motion. From what I've gathered, the energy or time required to pull it off is infinite, but I can't find any equations or clear explanations as to why or how that is. And I also don't know if there's any other reasons beyond that. If you could give me a thourough a breakdown for how absolute zero is impossible as you possibly could, I'd greatly appreciate it. Take as much extra time as you need. As long as it's detailed and correct I'm happy. Though ideally I would before it come in before the end of the day.arrow_forward
