Why the rutherford atomic model can't explain the line spectra of the hydrogen atom?

The Rutherford Atomic Model is a scientific theory proposed by New Zealand physicist Ernest Rutherford in 1911. It describes the structure of an atom as a small, dense positively-charged nucleus surrounded by negatively-charged electrons orbiting the nucleus in specific energy levels.
The Rutherford Atomic Model explains the line spectra of hydrogen atoms by proposing that the electrons in the atom can only exist in specific energy levels, or orbits, around the nucleus. When an electron jumps from a higher energy level to a lower one, it emits a specific amount of energy in the form of light, creating a unique line in the spectrum. This explains the discrete lines seen in the hydrogen atom's emission spectrum.
The line spectra of an element provide important information about the structure of its atoms. By observing the wavelengths of the spectral lines, scientists can determine the energy levels of the electrons in the atom and gain insight into the arrangement and behavior of these particles. This allows for a better understanding of the fundamental building blocks of matter.
The Rutherford Atomic Model differs from previous models, such as the Thomson and Bohr models, by proposing that the positive charge of an atom is concentrated in a small, dense nucleus rather than being evenly distributed throughout the atom. It also takes into account the specific energy levels of electrons, rather than the continuous orbits proposed by Bohr.
While the Rutherford Atomic Model was groundbreaking and provided a better understanding of atomic structure, it has some limitations. It does not fully explain the behavior of subatomic particles, such as electrons, which exhibit both wave-like and particle-like properties. It also does not account for the concept of quantum mechanics, which is necessary to fully understand the behavior of atoms and their particles.
