  The Physics Classroom serves students, teachers and classrooms by providing classroom-ready resources that utilize an easy-to-understand language that makes learning interactive and multi-dimensional....

• Physics Tutorial: Nodes and Anti-nodes

  One characteristic of every standing wave pattern is that there are points along the medium that appear to be standing still. These points, sometimes described as points of no displacement, are referr...

• Physics Tutorial: The Law of Reflection

  Light is known to behave in a very predictable manner. If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a...

• Physics Tutorial: The Mirror Equation

  While a ray diagram may help one determine the approximate location and size of the image, it will not provide numerical information about image distance and object size. To obtain this type of numeri...

• Physics Tutorial: Reflection, Refraction, and Diffraction

  The behavior of a wave (or pulse) upon reaching the end of a medium is referred to as boundary behavior. There are essentially four possible behaviors that a wave could exhibit at a boundary: reflecti...

• Physics Tutorial: Ray Diagrams - Concave Mirrors

  A ray diagram shows the path of light from an object to mirror to an eye. Incident rays - at least two - are drawn along with their corresponding reflected rays. Each ray intersects at the image locat...
