Question

What is the primary reason we used Balmer series in the lab this week, not Lyman series?

Question 7 options:

The voltage applied across the tube is not sufficient enough to produce Lyman emissions.

The spacing d of the diffraction grating is too small for the wavelengths of Lyman series, so their diffraction peaks are not produced.

Lyman series emissions have wavelengths too short to be seen.

The diffraction grating produces bright fringes of Lyman series at angles too small to be measured with the apparatus.

when ni = 2 and nf = 1

emited photon wavelength, lamda_max = 121.6 nm

when ni = infinite, nf = 1

emited photon wavelength, lamda_min = 91.18 nm

these wavelenghs smaller than visible light wavelength.
