Plz solve this

Dear student

n_{1} = 1, n_{2} = 2 E = - 2.178 \times 10^{- 18} \frac{Z^{2}}{n^{2}} ∆ E = E_{2} - E_{1}; ∆ E = \frac{h c}{λ} ∆ E = - 2.178 \times 10^{- 18} [\frac{1}{{n_{1}}^{2}} - \frac{1}{{n_{2}}^{2}}] ∆ E = 2.178 \times 10^{- 18} [\frac{1}{{n_{2}}^{2}} - \frac{1}{{n_{1}}^{2}}] ∆ E = 2.178 \times 10^{- 18} [\frac{1}{1^{2}} - \frac{1}{2^{2}}] = \frac{h c}{λ}

2.178 \times 10^{- 18} [\frac{1}{1} - \frac{1}{4}] = \frac{6.62 \times 10^{- 34} \times 3 \times 10^{8}}{λ} 2.178 \times 10^{- 18} [\frac{3}{4}] = \frac{6.62 \times 10^{- 34} \times 3 \times 10^{8}}{λ} λ = 1.21 \times 10^{- 7} m
