With some manipulation, the Rydberg equation can be rewritten in the form


E=constant×(1nf2−1ni2)


which allows you to calculate the energy of the emitted light. Express this constant in terms of the constants h, c, and RH using relationships between wavelength and energy as well as the Rydberg equation from the introduction.


Express the constant in terms of h and c, and RH.

Answer:

attached below is the detailed solution

answer : value of constant = 2.18 * 10^-18 J

Explanation:

Express the constant in terms of h and c and RH

attached below is the detailed solution

Constant = [tex]h_{C} R_{H}[/tex]

               = ( 6.626 * 10^-34 ) * ( 3 * 10^8 ) * ( 1.097 * 10^7 )

               = 2.18 * 10^-18 J

The Planck equation and the light speed  allow us to find the results for the transformation of the Rydberg equation are:

   [tex]E = A ( \frac{1}{n_1^2}\frac{x}{y} - \frac{1}{n_2^2} )\\A= R_H \ h \ c \\A = 2.18 \ 10^{-18} j[/tex]

The Rydberg equation is an empirical expression that explains the wavelength of the emissions.

          [tex]\frac{1}{\lambda } = R_H ( \frac{1}{n_1^2} - \frac{1}{n_2^2} )[/tex]  

Where λ is the wavelength of the emitted radiation, is the Rydberg constant, n₁ and n₂ are integers with n₁ <n₂

It is asked to write the Rydberg equation  for the energy.

Let's use the Planck relation.

           E = h f

The light speed is related to the wavelength and frequency of radiation.

           c = λ f

           

Where E is the energy, h the Planck constant, c the speed of light, λ the wavelength and f the frequency.

Let's  substitute.

           E = [tex]\frac{hc}{\lambda}[/tex]  

           [tex]\frac{1}{\lambda} = \frac{E}{hc}[/tex]  

Let's substitute in the Rydberg equation.

          [tex]\frac{E}{hc} = R_H ( \frac{1}{n_1^2} - \frac{1}{n_2^2}) \\E = R_H \ h \ c \ ( \frac{1}{n_1^2} - \frac{1}{n_2^2} )[/tex]

We can write is an constant of the form.

          A = [tex]R_H h c[/tex]

The value of the constant is :          

          A = 1,097 10⁷ 6,626 10⁻³⁴ 3 10⁸

          A = 2.18 10⁻¹⁸ J

In conclusion, using the Planck equation and the light speed we can find the results for the transformation of the Rydberg equation are

        [tex]E = A ( \frac{1}{n_1^2} - \frac{1}{n_2^2} )\\ A = R_H h c\\[/tex]

       A = 2.18 10⁻¹⁸ J
