So if you do the math, you can use the Balmer Rydberg equation or you can do this and you can plug in some more numbers and you can calculate those values. Determine likewise the wavelength of the third Lyman line. It was also found that excited electrons from shells with n greater than 6 could jump to the n=2 shell, emitting shades of ultraviolet when doing so. These are caused by photons produced by electrons in excited states transitioning . Of course, these lines are in the UV region, and they are not visible, but they are detected by instruments; these lines form a Lyman series. For example, the (\(n_1=1/n_2=2\)) line is called "Lyman-alpha" (Ly-), while the (\(n_1=3/n_2=7\)) line is called "Paschen-delta" (Pa-). His number also proved to be the limit of the series. Let us write the expression for the wavelength for the first member of the Balmer series. As you know, frequency and wavelength have an inverse relationship described by the equation. So we have an electron that's falling from n is equal to three down to a lower energy level, n is equal to two. this Balmer Rydberg equation using the Bohr equation, using the Bohr model, I should say, the Bohr model is what Download Filo and start learning with your favourite tutors right away!
