The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a...

When a conductor acquires an excess charge, the excess charge moves about and distributes itself about the conductor in such a manner as to reduce the total...

Electric charge possesses the energy required to do work upon devices placed within a circuit. Power refers to the rate at which charge does work upon these...

There are several methods for turning a neutral object into a charged object. All such methods involve a transfer of electrons onto or off of the object. The...

The Physics Classroom Tutorial presents physics concepts and principles in an easy-to-understand language. Conceptual ideas develop logically and sequentially,...

This video tutorial lesson explains what a work-energy bar chart is and discusses how to construct one. Five examples are done to illustrate the method of...

A sound wave is a mechanical wave that propagates along or through a medium by particle-to-particle interaction. As a mechanical wave, sound requires a medium...

This video tutorial lesson discusses the meaning of slope and the relationship between slope and velocity on a position-time graph. The procedure for...

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...

Traveling waves are observed when a wave is not confined to a given space along the medium. It is however possible to have a wave confined to a given space in...

This video tutorial lesson demonstrates how to draw a ray diagram for objects located in front of convex mirrors. The characteristics of the image are...

Many musical instruments consist of an air column enclosed inside of a hollow metal tube. If an end of the tube is uncovered such that the air at the end of...

Sound waves traveling through a fluid such as air travel as longitudinal waves. Particles of the fluid (i.e., air) vibrate back and forth in the direction that...

As we begin to apply our concepts of potential energy and electric potential to circuits, we will begin to refer to the difference in electric potential...

As light passes across the boundary from one material to another, it undergoes a change in speed. This change in speed is accompanied by a change in direction...

Reflection off of smooth surfaces such as mirrors or a calm body of water leads to a type of reflection known as specular reflection. Reflection off of rough...

Charging by conduction involves the contact of a charged object to a neutral object. Upon contact, there is a flow of electrons between objects, thus causing...

This video tutorial lesson explains what a pigment is and how it affects the color appearance of an object. The effect of combinations of pigments is discussed...

Charging by conduction involves the contact of a charged object to a neutral object. Upon contact, there is a flow of electrons between objects, thus causing...

Magnetic Fields and Electromagnetism explores the basic concepts which govern magnetic fields, magnetic forces, and the interrelation between electricity and...

The amount of energy that is transported by a sound wave past a given area of the medium per unit of time is known as the intensity of the sound wave....

Place a pencil in a glass filled with water and what do you notice? As you sight at the portion of the pencil that is submerged in the water, light travels...

This video tutorial lesson discusses the shape and features of a velocity-time graph for an object that is moving with constant speed. The distinctions of the...
