The question is not complete, here is the other part.

Assume that n = 1.36.

Express your answer to three significant figures and include the appropriate units.

λ =707.2nm

Explanation:

n = 1.36

t = 130

2 n t= (m+1/2) λ

To solve for λ.

λ = 2 n t ÷ m+1/2

λ = 2 × 1.36 × 130 ÷ m +1/2

λ =

If m= 0

λ= 353.6 ÷ 0+ 1/2

λ = 353.6 × 2

= 707.2nm

The expression for the change in energy for a transition from a state n_i

to a state n_f

in a hydrogen atom is
$\Delta E=-13.6 Z^2 ( \frac{1}{n_f^2}- \frac{1}{n_i^2} )[eV]$
where Z is the atomic number, which is 1 for hydrogen. Substituting n_i=3

and

we find
$\Delta E = -1.89 eV$
And to convert it into Joule, we should multiply this number by the elementary charge, obtaining:
$\Delta E = (-1.89 eV)(1.6 \cdot 10^{-19}c)=-3.03 \cdot 10^{-19}C$
