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. | \(\frac{20}{13}\lambda\) |
