As a fair warning; do not round the calculations/equations of the constants or your final answer will be marked incorrect! Input the non-rounded constants (i.e: 299792458 m/s for speed of light as opposed to the 3 * 10^8 demonstrated) or Aleks will mark the question incorrect (: Thank you for this video, explanation was great and easy to follow!

Yikes! That's really lame - sorry about that! I know that ALEKS doesn't tolerate rounding a lot of things, but I have never had a problem using 3 x 10^8 since most/all of the answers get rounded to 3 significant figures.

Hi Roxi, couldn’t we have just used the difference equation from the start? E = Ry*(1/(nf)^2 - 1/(ni)^2) and then plug the E into Planck’s equation. Aleks is brutal when you round in the intermediate steps

You absolutely can... and that would be WILD if you got the problem wrong using the equation that ALEKS actually puts into the problem for you to use, lol.
