SUMMARY
The discussion focuses on calculating the frequency and wavelength of a photon emitted when an electron transitions from the 4th energy level to the 3rd energy level in an atom. Using the energy difference of -0.33 x 10-18 J, the frequency is calculated using the equation E=hf, resulting in a frequency of 4.977 x 1014 Hz. The wavelength is then derived using the speed of light, yielding a value of 6.0277 x 1021 m, which is incorrect due to a calculation error in the frequency. The correct frequency should be expressed as 4.977 x 1014 Hz.
