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).
1.10. A beam of light with \ = 660 nm is reflected off a surface. The incident beam is normal to the
surface. If 1% of its energy is lost in the reflection, what is the change in momentum of the
reflected photons? How many photons must impact the surface per second if the intensity of
the source is 3 × 104 W/m²? Find the total change in momentum affecting that surface.
