Question

calculate the wavelength of radiation which excites the electrons of hydrogen atom from ground state to fourth energy level ionisation energy of hydrogen atomis1312kh/mole​

Answer 1

Answer:

The wavelength of radiation which excites the electron from ground state to fourth energy level is 97.3 nm

Explanation:

The problem can be solved using Rydberg's formula for wavelength which is given below.

Here n1 < n2

The electron jumps from ground state for which n1 = 1 to fourth energy level which is n2 = 4.

The Rydberg's constant for wavelength is 1.097 x 10⁷ m⁻¹.

Let us plug in the above values in the given formula.

The wavelength of radiation which excites the electron from ground state to fourth energy level is 97.3 nm or 9.73 x 10⁻8 m
