Question

2 to n=3 in the hydrogen 38. (5 pts) Calculate the wavelength of light associated with the transition from n atom. 39. (2 pts) In the preceding question, would light be absorbed or emitted by the atom?

Answer 1

38)

1/lambda = -R* (1/nf^2 - 1/ni^2)

R is Rydberg constant. R = 1.097*10^7

1/lambda = - R* (1/nf^2 - 1/ni^2)

1/lambda = - 1.097*10^7* (1/3^2 - 1/2^2)

lambda = 6.606*10^-7 m

lambda = 661 nm

Answer: 661 nm

39)

Electron is moving from lower energy state to higher energy state.

So, energy is being absorbed.

So, photon is being absorbed

Answer: absorbed
