{v_1}

is the frequency of the series limit of Lyman series,

{v_2}

is the frequency of the first line of Lyman series and

{v_3}

is the frequency of the series limit of the Balmer series. Then

View answer and explanation

Correct option: A

{v_1} - {v_2} = {v_3}

Option A (

{v_1} - {v_2} = {v_3}

) is correct because the frequency of the series limit of the Lyman series minus the frequency of the first line of the Lyman series equals the frequency of the series limit of the Balmer series.

Which of the following statements are true regarding Bohr’s model of hydrogen atom

(I) Orbiting speed of electron decreases as it shifts to discrete orbits away from the nucleus

(II) Radii of allowed orbits of electron are proportional to the principal quantum number

(III) Frequency with which electrons orbit around the nucleus is discrete orbits is inversely proportional to the cube of principal quantum number

(IV) Binding force with which the electron is bound to the nucleus increases as it shifts to outer orbits

50 \mathrm{~nm}

. Assuming that the entire photon energy is taken up by electron with what KE will the electron be emitted. In a spectrum of hydrogen atom, the ratio of shortest wavelength in Lyman series to longest wavelength in Paschen series is When the wave of hydrogen atom comes from infinity into the first orbit then the value of wave number is To explain his theory, Bohr used
