The quantum world of atoms, molecules, and photons is plagued by strange and paradoxical phenomena that challenge all our intuitions. (i) The radiant energy which is emitted or absorbed by the black body is not continuous but discontinuous in the form of small discrete packets of energy, each such packet of energy is called a 'quantum'. • Explain the Compton effect and describe it in terms of the momentum and energy of the photon. As things turned out, Planck’s hypothesis was the seed from which modern physics grew. • Describe experiments that demonstrate the particle-like properties of electro-magnetic radiation. At the same time it has helped make sense of a whole range of pe- 6) State the concept of wave-particle duality, and explain why E v (or) E = hν were ν is the frequency of radiation and h is Planck’s constant having the value 6.626×10-27 erg–sec or 6.626×10-34 J–sec. for black-body radiation is described by the Planck formula (Figure 10.1), u(”)d” = 8…h”3 c3 1 (eh”=kT ¡1) d” (10.1) where Planck’s constant, h = 6:626 £ 10¡34 J s. In this lecture, we demonstrate why quantum con-cepts are necessary to account for this formula. Introduction from the course in quantum physics you can find here: https:www.udemy.comquantum-physics The historical point of departure. 3) Allowed and forbidden energy bands (Chap. Quantum theory for semiconductors (Chap. In the case of light, the quantum is known as a photon. It has prompted a fundamental rethinking of physical theory. (iii) The energy of a quantum is directly proportional to the frequency of the radiation. 5) State the correspondence principle and explain its significance. 27.1 Waves Behave Like Particles 626 Quantum Theory FIGURE 27–1 This graph shows To explain these radiations, max planck put forward a theory known as planck’s quantum theory. max properties of nickel alloys pdf planck quantum theory properties of concrete for use in eurocode 2 pdf ppt Radiation was taken on by the young ambitious physicist Max Planck in his role as. Planck worked on the Blackbody radiation problem Plank was hired by electrical companies to find a way to produce the most light (radiation) using the least amount of energy possible. quantum theory can explain it, whereas the wave theory cannot. 3.1) Also refer to Appendices: Table B 2 (Conversion Factors), Table B.3 (Physical Constants), and Tables B.4 and B.5 Si, Ge, and GaAs key attributes and properties. Since then, the chunkiness of Nature (or at least of our theories about it) has been built into our basic conception of the world. since Max Planck introduced the element of dis-continuity we call the quantum a century ago. The programme to derive this formula is as follows. Planck thus returned to Newton’s corpuscular theory of light, which had been replaced by Maxwell’s wave theory in the late 19th century, now in a combination with the new particle statistics of thermodynamics developed by Ludwig Boltzmann. Max Planck explain the spectral distribution of blackbody radiation as result from oscillations of electrons. This Chemistry video explains what is Planck’s quantum theory of radiation. According to Planck: E=h$\nu$, where h is Planck’s constant (6.62606957(29) x 10-34 J s), ν is the frequency, and E is energy of an electromagnetic wave. In time, a theory might be developed to explain that law. Planck is considered the father of the Quantum Theory. Similarly, oscillations of electrons in … 3) Use quantum theory to explain features mentioned in (2) above 4) State the Wilson-Sommerfeld quantization notes and apply the same to derive the Planck’s quantization law and the Bohr’s quantization rule.
