The following solution is suggested to handle the subject “**1) Determine the wavelength of light emitted when an electron in a hydrogen atom makes a…**“. Let’s keep an eye on the content below!

## Question “1) Determine the wavelength of light emitted when an electron in a hydrogen atom makes a…”

1) Determine the wavelength of light emitted when an electron in

a hydrogen atom makes a transition from an orbital in n = 6 to an

orbital in n = 5.

2) Determine the wavelength of the light absorbed when an

electron in a hydrogen atom makes a transition from an orbital in

which n = 2 to an orbital in which n =3

## Answer

Answer (1) (2)

Rydberg equation can be used

R _{H} = Rydberg Constant. 2.18

10 ^{. -18}.

n _{f} = final level of energy

n_{i} = initial energy level

Therefore,

1) Transition from n=6 – n=5

n _{f} = 5.

n _{i} = 6.

2.18 J [(1/62] – (1/52)] =.-2.66 *10-20 J (-ve Sign refers to energy released)

We know.

where h=6.626 10 ^{-34}Js and c=3

10 ^{8} m/s

so,

(6.626

10-34 Js

3

108 m/s) / (2.66 * 10-20 J) = 7.47

10-6 m = 7472nm

2) Transition from n=2 – n=3

n _{f} = 3.

n _{i} = 2.

2.18 J *

10-18 J [(1)/22) – (1/32)] =3.03 * 10-19 J

(6.626

10-34 Js

3

108 m/s) / (3.03

10-19 J) = 6.56

10-7 m = 656nm

## Conclusion

Above is the solution for “**1) Determine the wavelength of light emitted when an electron in a hydrogen atom makes a…**“. We hope that you find a good answer and gain the knowledge about this topic of **science**.
