Δ E for breaking one Cl-Cl bond = 242 k J / m o l Δ E 242 \times 1 0^{3} J or λ = \frac{N _{A} h c}{λ} = \frac{6.02 \times 1 0 ^{23} \times 6.62 \times 1 0 ^{- 34} \times 3.0 \times 1 0 ^{8}}{λ} = \frac{6.02 \times 1 0 ^{23} \times 6.62 \times 1 0 ^{- 34} \times 3.0 \times 1 0 ^{8}}{242 \times 1 0 ^{3}} = 4.94 \times 1 0^{- 7} m or 494 \times 1 0^{- 9} m = 494 nm
