The Photoelectric Effect When electromagnetic radiation, such as light, hits the surface of a metal electrons are emitted. These electrons…
Pressure Pressure – force per unit area. The following equation can be used to calculate pressure (P): Where F is…
Wave Speed – the distance a wave travels per unit time. From kinematics we know that speed is equal to…
Transverse Waves For transverse waves the displacement of the particles is perpendicular to the direction of wave travel. In other…
Electromagnetic Waves Electromagnetic waves are transverse waves with different frequencies that make up the electromagnetic spectrum. The waves are created…
Stress Stress (σ) – the force per unit cross sectional area applied to an object. From this definition we have…
If we plot the elastic deformation of a spring we usually get a graph that looks like Graph 1: NOTE:…
If a large enough force is applied to a solid object the shape of the object can change. This change…
Waves are a transfer of energy that can be described as vibrations (or oscillations) about a rest point. Below is…
Kirchhoff’s First Law Kirchhoff’s first law is a consequence of the conservation of charge and states that: The sum of…
