The wave number of the shortest wavelength of absorption spectrum of hydrogen atom is _____ (Rydberg constant .=109700 ~cm ⁻¹ ) .

Correct answer

109700

Step-by-step solution

Given, R=109700 ~cm ⁻¹ Shortest wavelength mean transition is from infinity to n=1 . Using the formula, aligned & v =R [ 1 n_f^2 - 1 n_i^2 ] & n_t= , n_i=n=1 & v =109700 [ 1 1 - 1 ] & v =109700 ~cm ⁻¹ aligned
