When white light passes through a prism it spreads out into all the colors of the rainbow. Physics tells us this results from refraction and dispersion.

In electrical circuit elements the resistance in ohms, potential difference in volts, and current in amps are related by Ohm's law.

Ultrasound imaging is a safe noninvasive technique for making diagnostic medical images of the human body. What physics makes this technique work?

The latent heats of fusion and vaporization tell us how much energy is needed for transitions between the liquid and solid phase or between gas and liquid phases.

Convection currents are one of the three ways to transfer heat energy that works in either a liquid or a gas.

A changing magnetic field will induce an electric current and corresponding electric potential difference according to Faraday's Law of electromagnetic induction.

Lenz's law, giving the direction of induced electromagnetic fields, is a consequence of the law of conservation of energy.

Pascal's principle, along with the relationship among pressure, force, and area, forms the basic foundation for all hydraulic engineering.

Collisions problems are an important class of problems in physics. Momentum is conserved in all collisions. Kinetic energy is only conserved in elastic collisions.

Momentum is the mass times the velocity. In the absence of external forces, the total momentum of an isolated system must be conserved and remain constant.

In physics pressure is the force per unit area. There are many applications of this concept.

The minimum speed needed to escape from the gravitational field of a star, planet, or moon is the escape velocity. Escape velocity derives from conservation of energy.

A Faraday cage is an enclosed conducting shell that shields its interior from strong electric fields and electromagnetic waves.
