Answer:
3
Explanation:
1/λ = R (1/n1^2 -1/n2^2)
Where;
λ= wavelength = 1094 nm
R = Rydberg constant = 1.0974 * 10^7 m-1
n1 = lower energy level =?
n2= higher energy level =6
1/1094 *10-9= 1.0974 * 10^7(1/n1^2 - 1/36)
(1094 *10-9)^-1/1.0974 * 10^7 =(1/n1^2 - 1/36)
0.083 = (1/n1^2 - 1/36)
0.083 + 1/36 =1/n1^2
0.111 =1/n1^2
n1^2 = 9
n1 =3
