If an electron in a hydrogen atom jumps from the \(3^{\text{rd}}\) orbit to the \(2^{\text{nd}}\) orbit, it emits a photon of wavelength \(\lambda\). When it jumps from the \(4^{\text{th}}\) orbit to the \(3^{\text{rd}}\) orbit, the corresponding wavelength of the photon will be:
1. \(\frac{16}{25}\lambda\)
2. \(\frac{9}{16}\lambda\)
3. \(\frac{20}{7}\lambda\)
4. \(\frac{20}{13}\lambda\)
