frequencies of the atomic emission spectrum of hydrogen were predicted for the first time by the model of the atom.

Explanation:

The Bohr model of the atom was the first to predict the frequencies of the atomic emission spectrum of hydrogen. Niels Bohr proposed this model in 1913. It introduced the concept of quantized energy levels for electrons in an atom. Electrons can only exist in certain discrete energy levels. When an electron transitions from a higher - energy level to a lower - energy level, it emits a photon with a frequency corresponding to the energy difference between the two levels. The formula for the frequency of the emitted photon is \(v=\frac{E_{2}-E_{1}}{h}\), where \(E_{2}\) and \(E_{1}\) are the energies of the higher and lower energy levels respectively, and \(h\) is Planck's constant. This model was able to explain the hydrogen emission spectrum, which consists of discrete lines at specific frequencies.
