Photoelectric Effect Grade 12 Physical Sciences November 2021 This resource will enable you to revise and consolidate the content on photo electric effect. The photoelectric effect refers to the emission of electrons from a material when it is exposed to light of a sufficiently high frequency or energy. this phenomenon occurs due to the interaction between photons (light particles) and electrons in the material.

Photoelectric Effect Grade 12 | Part 3

Photoelectric Effect Grade 12 | Part 3 Photoelectric effect is the phenomenon where light of particular frequency causes electrons to be ejected from a metal surface. dual nature of light – light can be explained in two ways; light having a wave nature and light having a particle nature. work function – the minimum energy package needed to eject an electron from a metal surface. In an experiment to demonstrate the photoelectric effect, light of different wavelengths was shone onto a metal surface of a photoelectric cell. the maximum kinetic energy of the emitted electrons was determined for the various wavelengths and recorded in the table below. You’ll learn: 🔹 what the photoelectric effect actually is 🔹 the historical expectations of light and why they were wrong 🔹 how to calculate the energy of a photon using planck’s. Let's explore how the quantum theory of light explains the below experimental results of photoelectric effects. 1. the kinetic energy of the photoelectrons are independent of intensity but depend on frequency. 2. below a minimum frequency called the threshold frequency, no photoelectric effect takes place, even if the light has very high intensity. 3. photoelectric effect is almost instantaneous.

Each incident photon would transfer all its energy to one electron in the metal. the photoelectric effect is the process whereby an electron is emitted by a substance when light shines on it. einstein received the 1921 nobel prize for his contribution to understanding the photoelectric effect. By following these revision notes and actively engaging with the material, students should be well prepared to understand and apply the concepts of the photoelectric effect in various contexts. Photoelectric effect grade 12 physical science revision notes: the photoelectric effect is the process that occurs when electromagnetic radiation (light) shines on a metal surface and ejects electrons from the metal. Summarised explanations of how photoelectric effect works and the relationship between the energy, frequency and kinetic energy.
