Chem 1045 Line Spectra 2 of 7 The energy emitted or absorbed appears as some sort of radiation with a characteristic wavelength: Since the electron can only exist in certain main energy levels, the transitions between energy levels only involve certain energies and only certain wavelengths of radiation are emitted (or absorbed). The wavelengths absorbed or emitted make up a _________________________________ The wavelength emitted or absorbed during an electron transition can be calculated: -1 2 2 1 2 1 1 1 = 0.0109737 nm - n n λ

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
