Measuring the Hydrogen Balmer Series and Rydberg's Constant
The Balmer series is a set of discrete emission spectral lines of the Hydrogen atom. The diffractive grating is used to disperse the collimated beam of hydrogen deuterium lamp, and the diffractive angle of Balmer series line is measured by digital protractor and telescope. The experimental value of Rydberg constant is derived from the wavelength.
