Task 1: Quantum Physics In this unit, you were introduced to and learned how to use the following equations: Energy unit conversions between electron volts (eV) and joules, (J); Einstein's photon energy equation; Compton's momentum equation; • de Broglie's wavelength equation Using your knowledge of these equations, quantitatively compare a 3.1 eV photon and a 3.1 eV electron by completing the following data table: Use the following Task 2 Data Table document to complete this task. Note: For any required calculation, be sure to include both your calculation and your answer. You may type out your answers, save your document as a PDF file then submit your work. Property Energy (J) Rest mass (kg) Speed (m/s) Wavelength (m) Momentum (kg•m/s) Photon Electron leted
Particle Theory of Light
The particle theory of light was the proposal made by Newton in 1704 in his treatise Opticks. This is the most basic light theory, in which light is thought to be made up of microscopic particles known as "corpuscles" and that's why this particle theory of light is also named as Corpuscular theory of light.
Stopping Potential
In an experiment conducted by Heinrich Hertz, an apparatus was made where the incident light was made to fall on the metallic plate, it was discovered that metals emit electrons. The surface electrons are bound to metals with a minimum amount of energy and some of the incident photos enter the surface, they undergo collision with the atoms of the metal, they get absorbed and emit energy to an election, making it photoelectron, where the collision between the photons and electrons ejects the electrons out of the metal and with a negatively charged electron, causes photocurrent and when this current passes it creates an electric field where there is a potential difference at the output due to the anode and cathode of the electrode of the apparatus. This study involves the theory of Quantum physics and electromagnetism involving electromagnetic radiation and electromagnetic wave theory.
Quantization of Charges
An electron is a negatively charged subatomic particle either attached to an an atom or sticks to the nucleus of the atom. Electrons exert the negative charge that tries to balance the positive charge of the nucleus.
