Question Completion Status: QUESTION 1 Photons traveling from the center of the Sun towards its surface can take to make the journey. O a. a few hours Ob.hundreds of years Ochundreds of thousands of years O d. billions of years QUESTION 2 A photon that passes through the atoms in the Sun's atmosphere without being absorbed is a continuum photon O True O False QUESTION 3 Because photons with wavelength of 656 nm are line photons for transition between the n-2 and n-3 levels of the hydrogen atom, photons of this wavelength must also be line photons for all other atoms. O True O False

Explanation / Answer

hundreds of thousands of years.  it takes many thousands of years for a photon to get from the core to the surface of the sun.

True. Continuum photons do not have the right amount of energy to interact easily with the atoms. Therefore they mostly pass through the gas without interacting at all.

false. Spectral lines are highly atom-specific. Thus the photons may need not be line photons for all other atoms.
