What is the approximate wavelength of the radiation emitted when the electron in an hydrogen atom jumps from n = ∞ to n = 3 ? |
822 Å 822 nm 8220 nm 365 nm |
822 nm |
$ \frac{1}{\lambda} = R(\frac{1}{3^2} - \frac{1}{\infty^2}) = \frac{R}{9}$ $\Rightarrow \lambda = \frac{9}{R} \approx 8220A^o = 822 nm $ |
