Question

Determine the energy of the wave when an electron makes the jump from the following energy levels:

a. N = 1 to N = 4
b. N = 2 to N = 3
c. N = 4 to N = 7

type out the process please!​

Answer 1

Ok so for this question we need to use the Rydberg equation.
1/lambda = R * (1/nf^2 -1/ni^2)
R is the Rydberg constant of 1.097 *10^7
So you get 1/lambda = (1/4^2 -1/1^2)*1.097*10^7
As shown in the first photo
You can use the formula to plug in for any of the questions
Nf is the final energy level
Ni is the initial energy level
