Question

The energy E of the electron in a hydrogen atom can be calculated from the Bohr formula: E= Ry In this equation Ry stands for the Rydberg energy, and n stands for the principal quantum number of the orbital that holds the electron. (You can find the value of the Rydberg energy using the Data button on the ALEKS toolbar) Calculate the wavelength of the line in the absorption line spectrum of hydrogen caused by the transition of the electron from an orbital with n=1to an orbital with n =7. Round your answer to 3 significant digits.

Ry=2.17987x10^-18 J​

Answer 1

Answer: So to solve, for this we're going to use the equation 1 over the wave length is equivalent to reitberg's constant multiplied by 1, over n, lower energy level square that and then 1 over n h, higher energy level and then square that also so plugging the information That we have our is rydberg's constant, 1.097 times 10 to the 7 per meter. Then lower energy level is 7 square and then the higher energy level is 12 square, also calculating this we'll get 147696.995. This is me, then. We still have here 1 over the wave. Blank so we'll take the inverse of outside of the equation to solve, for the wave length will get 6.7 times centene 6. This is the mess there's no specific unit. In our final answer, there's no required specific unit, so i will leave our final answer in terms of me. That'S it done.
