Davisson and Germer experiment : If electrons were considered as particles, draw a graph of the...

Particle physics can be described using the standard model, which demonstrates the interaction of the four forces between particles: electromagnetism, gravity, and strong and weak nuclear force. Learn to identify the particles of the standard model and also the limitations in its use.

Understand what wave particle duality is by learning its definition. Know how light behaves like a particle and see evidence that light is a particle.

Understand the principle of thin-film interference. Learn about the various equations used to calculate different parameters of thin-film interference.

Diffraction is the spreading of a wave when encountering an obstacle, or a slit. Discover different types of diffraction in real-life examples, and explore Huygen's principle that explains the observed behavior of waves and wavelets.

Wien's Law and the Stefan-Boltzmann Law explain how objects get brighter when they get hotter and how temperature impacts color. Discover blackbody radiation and temperature and explore why hotter equals brighter and how the changes in brightness and color can be explained with Wien's Law and the Stefan-Boltzmann Law.

Learn what length contraction has to do with the speed of light, and why we don't notice it in every day life. Also learn a little about other relativity topics that will help you understand length contraction better.

In this lesson, magnetic flux and motional EMF are explained. Lenz's law is also introduced.

Einstein's special theory of relativity can be applied to solve problems regarding relativistic mass, length contraction, and time dilation. This lesson analyzes the equations that Einstein developed with some practice problems to aid in understanding.

This lesson focuses on the Zeroth Law of Thermodynamics. It contextualizes it with the first, second, and third laws. It also discusses examples and the importance of the zeroth law.

Learn about the special theory of relativity. Understand what special relativity is and how it was developed. Know the theory of relativity equation.

Learn about interferometers and understand the working principles of the famous Michelson interferometer. See the applications of the Michelson interferometer.

Scanning electron microscopes create images using electrons in the place of light. Take a look at the definition of a scanning electron microscope and explore how it works and what it's used for.

Learn about paramagnetic and diamagnetic. Understand what diamagnetic is, read a detailed definition of paramagnetic, and see examples of these two concepts.

Hans Christian Oersted progressed the scientific understanding of magnetic fields and electricity through his famous experiment of a compass. Identify how his experiment demonstrated the effect of current on electromagnetism and the results of his discovery.

Understand Kepler's three laws of planetary motion. Know how Kepler's work with Tycho Brahe helped in the formulation of these laws.

Lanthanides, or rare earth metals, are a group of 15 chemical elements that are silver in color and can tarnish when exposed to oxygen in the air. Learn more about the definition of lanthanides by exploring their characteristics, properties, and uses, such as coloring ceramics.
