Question

Question 9 3 pt: Photons of light with an energy of 122 nm are being directed through a chamber of hydrogen gas atoms. The gas atoms began in their ground state (n=1) and, after interacting with these photons, some move to (n=2). Which of the following statements is true? If photons with a slightly longer wavelength had been used, such as 128 nm, more electrons would have moved to n=2 If photons with a slightly shorter wavelength had been used, such as 118 nm, more electrons would have moved to n-2. Photons will eventually be emitted and their wavelength will also be 122 nm. The electrons are now "trapped in the n2 electronic energy level and will stay there.

Answer 1

a b c where ha plank constant. - speed of light Eat - wavelengths solution as you conace the energy is inversely precapastal to wavelength, so if we increases wavelength , Energy will decreases so less amaunt of é would have movedo because more photons used not to move Q é and if we decreases wavelenith Energy will increases, so mare é would have moved to n=2. because now less no of photons is used to moue é o and after reaching n=2, nowe, e meant to decreases it conergy, and as we read above, 3 photons wild to mave e fecom nal to n=2 but not é realese combined ok 3 é, xo, emmited wavelengt will be shater than 122nm. a Thank you
