Quantum theory explains black-body radiators by introducing the concept of quantized energy levels, which led to the understanding of how objects emit and absorb electromagnetic radiation. Classical physics failed to accurately describe this phenomenon, leading to the "ultraviolet catastrophe." Max Planck resolved this by proposing that energy is emitted in discrete packets called "quanta," leading to Planck's law of black-body radiation. This law accurately describes the spectral distribution of radiation emitted by a perfect black body at thermal equilibrium.

How did max planck called an object radiated energy?
Max Planck called an object radiating energy a "blackbody." He developed a theoretical model to explain the energy distribution of radiation emitted by a blackbody at different temperatures, leading to the development of quantum theory.
Who discovered blackbody radiation?
Blackbody radiation was discovered by Max Planck in 1900. Planck proposed a theory that described the spectral distribution of energy emitted by a blackbody at different temperatures, leading to the development of quantum mechanics.
Can you provide some examples of blackbody radiation and explain their significance in physics?
Blackbody radiation refers to the electromagnetic radiation emitted by a perfect absorber and emitter of radiation, known as a blackbody. Examples of blackbody radiation include the radiation emitted by stars, such as the Sun, and the thermal radiation emitted by objects at high temperatures, like a heated metal rod. In physics, blackbody radiation is significant because it helped to develop the understanding of quantum mechanics and the concept of energy quantization. The study of blackbody radiation also led to the development of Planck's law, which describes the spectral distribution of radiation emitted by a blackbody at a given temperature. This law played a crucial role in the development of modern physics and the theory of quantum mechanics.
What is quantum free electron theory of metal?
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.
What scientist used quantum theory and a planetary model of the atom to explain the hydrogen spectrum?
Bohr.
Can anyone explain the quantum theory?
Richard Feynman stated once that "if you think you understand quantum mechanics then you don't understand quantum mechanics". However it is possible to learn how to write and solve the equations of quantum mechanics to get answers that can be verified experimentally.
What are the two ideas leading to a new quantum mechanics?
The two key ideas leading to a new quantum mechanics were Planck's notion of quantized energy levels in blackbody radiation, and Einstein's explanation of the photoelectric effect using quantized light particles (photons). These ideas challenged classical mechanics and paved the way for the development of quantum theory.
Why the classical theory of solids cannot explain the theory of solids?
The classical theory of solids is based on the assumption that atoms are fixed in a lattice structure and do not move. However, quantum mechanics shows that atoms in solids have wave-like properties and do exhibit movement. This discrepancy between classical theory and quantum mechanics makes classical theory inadequate for explaining the behavior of solids at the atomic level.
What is planks quantum theory?
explain planks quantum theory? Planck did not make the whole Quantom thoery. He only made up Quanta. Other scientists helped inprove it over time.

Who made the first use of quantum theory to explain the structure of atom?
Niels Bohr was the first to use quantum theory to explain the structure of the atom in his atomic model in 1913. He proposed that electrons orbit the nucleus at specific energy levels, or shells, and that energy is quantized in discrete amounts.
