Korzystając ze wzoru oblicz dł. fali R= 1,097 * 10^7 [1/m] n= 3

[latex] frac{1}{lambda} =R( frac{1}{2^2}- frac{1}{n^2} )\ frac{1}{lambda} =frac{R}{2^2}- frac{R}{3^2} \ frac{1}{lambda} =frac{R}{4}- frac{R}{9} \ frac{1}{lambda} =frac{9R}{36}- frac{4R}{36} \ frac{1}{lambda} =frac{5R}{36}\\ lambda= frac{36}{5R}= frac{36}{5cdot 1,097cdot 10^7} approx6,56cdot 10^{-7}m[/latex]
