The formula for this is E = hu, where E is the energy of the radiation, h is a universal constant known as Planck'sconstant, and u is the frequency of the radiation. This proposal-that the energy contained within a light beam is transferred in individual units, or quanta-contradicted a hundred-year-old tradition of considering light energy a manifestation of continuous processes.

When was the next really important breakthrough in the theory of matter?
A significant breakthrough in the theory of matter occurred in the early 20th century with the development of quantum mechanics, particularly through the work of physicists like Max Planck and Niels Bohr. Planck's introduction of quantized energy levels in 1900 and Bohr's model of the atom in 1913 fundamentally changed the understanding of atomic structure and behavior. This shift laid the groundwork for modern physics and our understanding of matter at the microscopic level.
What was Marsden' contribution to the atom?
what did marsden contribute to the evolution of the atom
What information Julius plucker contribute to the understanding of the atom?
Julius Plücker contributed to the understanding of the atom through his experiments with cathode rays in the mid-19th century. He demonstrated that these rays could be deflected by electric and magnetic fields, suggesting that they were composed of charged particles. This work laid the groundwork for later discoveries in atomic theory, particularly the identification of electrons as subatomic particles. Plücker's findings helped shift scientific focus towards the study of atomic structure and the behavior of particles within it.
What does planck's constant divided by 2times of pi indicates in Bohr's atomic theory?
In Bohr's atomic theory, Planck's constant divided by 2π represents the angular momentum of the electron in a stable orbit around the nucleus. This value is used to quantize the angular momentum of the electron in discrete levels, as proposed by Bohr in his model of the atom.
How did Thomson help the understanding of atom?
He discovered that the atom contained smaller particles called electrons.
What is asubatomic particle?
Subatomic particles are particles that are smaller than an atom, such as protons, neutrons, and electrons. They make up the structure of an atom and contribute to its properties and behavior. These particles are fundamental to understanding the world of particle physics.

How did the atom bomb contribute to the Cold War?
we were feared of due to the technology of the atom bomb.
How did Bohr improve Planck's theoory?
Bohr improved Planck's theory by incorporating the concept of quantized energy levels for electrons in atoms. He proposed that electrons could only exist in certain distinct energy levels, which helped explain the stability of atoms and the emission/absorption of light in atomic spectra. This led to the development of the Bohr model of the atom.

What information can be obtained from a coordination number table?
A coordination number table provides information about the number of atoms or ions surrounding a central atom in a compound. It helps in understanding the geometry and structure of the compound.
