Find the angular position of third spectral line in hydrogen

Reference no: EM13267435

The three principal visible spectral lines from hydrogen have wavelengths 434 nm, 486 nm, and 656 nm. The principal line of sodium is at 589 nm. A sodium lamp used to calibrate a diffraction grating shows the first-order sodium line at 25.6? from the central maximum.

Part A Find the angular position of the first spectral line in hydrogen (434 nm).

Part B Find the angular position of the second spectral line in hydrogen (486 nm).

Part C Find the angular position of the third spectral line in hydrogen (656 nm).
