A spectrophotometer is used to measure the absorption spectrum of an aqueous dye solution. An electronic transition in the dye molecule corresponds to an energy change of \(3.31 \times 10^{-19} \text{ J}\). What is the wavelength of the photon absorbed during this transition?

- **A.** \(2.00 \times 10^{-15} \text{ m}\)
- **B.** \(1.50 \times 10^{-7} \text{ m}\)
- **C.** \(6.00 \times 10^{-7} \text{ m}\)
- **D.** \(5.00 \times 10^{14} \text{ m}\)
