12.8 The radius of the innermost orbit of a hydrogen atom, $r_1$ = 5.3 $*{10}^{-11}$ m

Let $r_2$ be the radius of the orbit at n = 2. The relation between the radius of the orbit is

$r_2$ = $n^2*r_1$ =4 $*5.3*{10}^{-11}\mathrm{}\mathrm{m}$ =21.2 $*{10}^{-11}\mathrm{}\mathrm{m}$

Let $r_3$ be the radius of the orbit at n = 3. The relation between the radius of the orbit is

$r_3$ = $n^2*r_1$ =9 $*5.3*{10}^{-11}\mathrm{}\mathrm{m}$ =47.7 $*{10}^{-11}\mathrm{}\mathrm{m}$

City University of Seattle operates on an open admission policy, meaning that the university admits all applicants who meet the basic admission criteria. While specific GPA requirements are not explicitly stated, the primary requirement is a high school Diploma or equivalent for undergraduate programs and bachelor's degree from a recognised university or equivalent for graduate programs.
The eligibility criteria and document requirements might differ for different programs hence, it is recommended to refer the official site for programme specific requirements.

Hi, the top BTech colleges in Ernakulam are listed below:

Hope this helps!

12.6 For ground level, $n_1$ = 1

Let $E_1$ be the energy level at $n_1$ . From the relation

$E_1=\frac{E}{n_1^2}$ where E = -13.6 eV, we get

$E_1=\frac{E}{n_1^2}$ eV = -13.6 V

For higher level, $n_2$ = 4

Let $E_2$ be the energy level at $n_2$ . From the relation

$E_2=\frac{E}{n_2^2}$ where E = -13.6 eV, we get

$E_2=\frac{-13.6}{4^2}$ eV = -0.85 V

The amount of energy absorbed by proton is given as $E_p$ = $E_2-E_1$ = -0.85 + 13.6 eV = 12.75 eV = 12.75 $*1.6*{10}^{-19}$ J = 2.04 $*{10}^{-18}$ J

For a photon of wavelength $?,$ the expression of energy is written as

$E_p$ = $\frac{hc}{?}$ , where

c = speed of light = 3 $*{10}^8$ m/s

h = Planck's constant = 6.626 $*{10}^{-34}$ Js

We get $?=\frac{hc}{E_p}$ = $\frac{6.626*{10}^{-34}*3*{10}^8\mathrm{}}{2.04*{10}^{-18}}$ = 9.744 $*{10}^{-8}$ m = 97.44 nm

The frequency of the proton is given by,

$?=\frac{c}{?}$ = $\frac{3*{10}^8}{9.744*{10}^{-8}}$ Hz= 3.1 $*{10}^{15}$ Hz

12.5 Ground state energy of hydrogen atom, E = -13.6 eV

Kinetic energy is equal to the negative of the total energy (ground state energy) = 13.6 eV

Potential energy is equal to the negative two times of kinetic energy = -13.6 $*2=-27.2eV$

The City University of Seattle tuition cost at for international students differ and is programme specific. The average annual tuition for undergraduate programs is about USD 48,510 USD (INR 41 L). The average tuition for graduate programs is about USD 13,770 USD (INR 12 L), which makes them cheaper as compared to other universities in the US.  Below mentioned are tuition fees of specific programs offered in the university:

(USD 1 = INR 84.02)

12.4 Separation of two energy level of atom, E = 2.3 eV = 2.3 $*1.6*{10}^{-19}$ J = 3.68 $*{10}^{-19}$

Let $?$ be the frequency of radiation emitted when the atom transits from upper level to lower level.

We have the relation for energy as $E=h?$  , where

h = Planck's constant = 6.626 $*{10}^{-34}$ Js

Then $?=\frac{E}{h}$ = $\frac{3.68*{10}^{-19}}{6.626*{10}^{-34}}$ Hz = 5.55 $*{10}^{14}$ Hz

Hence the frequency is 5.55 $*{10}^{14}$ Hz

City University of Seattle acceptance rate is exceptionally high, at 100%. This shows that the university is an open choice for potential students because it accepts all applicants who fulfill the minimum requirements for admission. There can be some program specific requirements so it is always advisable to refer to the official program page. The goal of the open admissions system is to assess candidates holistically rather than just based on their performance on standardized tests. This strategy supports CityU to offer education opportunities to a wide variety of students around the world based on their potential.

12.3 Rydberg's formula is given as:

$\frac{hc}{?}$ = 21.76 $*{10}^{-19}\left[\frac{1}{n_1^2}-\frac{1}{n_2^2}\right]$

Where, h = Planck's constant = 6.6 $*{10}^{-34}$ Js

c = speed of light = 3 $*{10}^8$ m/s

$?$ = Wavelength

$n_1$ and $n_2$ are integers.

The shortest wavelength present in the Paschen series of the spectral lines is given for the values $n_1=3$ and $n_2=?$

Therefore, $\frac{hc}{?}$ = 21.76 $*{10}^{-19}\left[\frac{1}{3^2}-\frac{1}{{?}^2}\right]$

$\frac{hc}{?}=$ 2.42 $*{10}^{-19}$

$?=\frac{6.6*{10}^{-34}*3*{10}^8}{2.42*{10}^{-19}}$ = 8.189 $*{10}^{-7}$ m= 818.9 nm
