Basic Quantum Physics Verified Answers What is Quantum Physics? ️Quantum physics is a branch of science that deals with discrete, indivisible units of energy called quanta as described by the Quantum Theory. Quantum Theory ️There are five main ideas represented in Quantum Theory: 1.Energy is not continuous, but comes in small but discrete units. 2.The elementary particles behave both like particles and like waves. 3.The movement of these particles is inherently random. 4.It...

Quantum Physics Test Questions and Answers Gravitational Force - Answer-acts over long distances Photoelectric Effect - Answer-light hits a metal plate energizing and ejecting an electron. Photon - Answer-a discrete packet of light If electrons are not being ejected from a metal plate what should you change about the light shining on it? - Answer-frequency In the double slit experiment electrons caused what to form on the screen behind? - Answer-Wave Interference Pattern The e...

Quantum Physics Study Guide There have been two models of light. What are they and who first supported each? Particle: Newton and wave: Huygens (1600s) What determines the color with which a body glows? temperature What is Planck's equation? E=hf What does Planck's equation mean? Energy comes in discrete packets. Energy of a photon is proportional to its frequency. What does Planck's equation explain? Blackbody radiation problem and the photoelectric effect What is Planc...

Quantum Physics-2024 Blackbody Radiation - ️️ - Radiation properties are independent of the material. The maximum of the distribution shifts to smaller wavelengths as the temperature is increased. The total power radiated increases with the temperature. One of the outstanding exceptions that classical physics could not explain, dubbed the "ultraviolet catastrophe" by Paul Ehrenfest. Blackbody - ️️ - Has the ideal property that it absorbs all the radiation falling on it and refle...

Quantum Physics Complete Guide Photon Particle of light Intensity + Formula Power per unit area I = P/A Units: W/m² The Photoelectric Effect The emmision of electrons from a metal when electromagnetic radiation of high enough frequency falls on the surface. Threshold Frequency (f₀) Minimum frequency of light needed to eject electrons fromt he surface of the metal Classical Theory Light acts as a wave and the energy of a wave depends on its amplitude (intensity) not its fre...
