Johann Jakob Balmer - Wikipedia, the free encyclopedia (328 words) |
 | Johann Jakob Balmer (May 1, 1825 – March 12, 1898) was a Swiss mathematician and an honorary physicist. |
| Balmer then used this formula to predict the wavelength for m = 7, and a colleague at the university was able to confirm a match to a high degree of accuracy. |
| Balmer crater on the Moon is named after him. |

| However, despite being a mathematics teacher and lecturer all his life, Balmer is best remembered for his work on spectral series and his formula, given in 1885, for the wavelengths of the spectral lines of the hydrogen atom. |
| It is surprising to realise that Balmer was sixty years old when he wrote the paper for which he is famous on the spectral lines of the hydrogen atom and that he was seventy-two when he wrote his only other work on this topic. |
| Putting m = 7 gave Balmer a predicted value for the next line and indeed a colleague at the University of Basel was able to tell Balmer that this line had been observed and the wavelength agreed with a high level of accuracy with the one Balmer's formula predicted. |
