Q31.For emission line of atomic hydrogen from ni = 8 to nf = n, the plot of wave number -v against n2 will be: (The Rydberg constant, RH is in wave number unit) (1) Linear with slope -RH (2) Non linear (3) Linear with slope RH (4) Linear with intercept -RH
What This Question Tests
This question tests the understanding of the Rydberg formula for the hydrogen spectrum and the ability to determine the nature of a plot when wavenumber is plotted against `n²` instead of `1/n²`.
Concepts Tested
Formulas Used
