Step-by-step solution
(A) For the lowest energy line of the Balmer series, n₁ = 2 and n₂ = 3 . Wavenumber = R_H ( 1 2^2 - 1 3^2 ) = 5R_H 36 . (B) For the series limit of the Lyman series, n₁ = 1 and n₂ = . Wavenumber = R_H ( 1 1^2 - 0 ) = R_H . (C) As the temperature of a blackbody increases, the peak of the emission curve shifts to a shorter wavelength. (D) In the photoelectric effect, increasing the intensity of incident light (keeping frequency constant and above threshold) increases the number of photons striking the surface per uni
