Concept of wavefront: wavefront is the locus of points characterized by propagation of positions of identical phase.

Concept of wave function: there is a mathematical function associated with every particle which behaves like the functions of other undulatory phenomena.

Concept of wave equation

Instrumento que mide el voltaje (caída de tensión o diferencia de potencial) entre los extremos de un elemento de un circuito eléctrico.

The voltmeter is an instrument which measures voltages (tensions or differences of potential) between both ends of an element in a circuit through which there is an electric current circulating.

Measure of the voltage. If you wish to measure the voltage in an electric circuit, you need a measuring device (multimeter)

La vida media representa el promedio de vida de un núcleo atómico de una muestra radiactiva.

Concepto de velocidad y masa de los electrones. Cuando sobre un tubo de rayos catódicos se sitúan un campo eléctrico y otro magnético, perpendiculares, puede estudiarse de manera cuantitativa las propiedades de los electrones: su velocidad, su carga y la relación carga/masa.

A particle which oscillates around a point of equilibrium, subject to a force proportional to the distance to this point, has a simple harmonic vibratory movement.

Concepto de vector desplazamiento

La velocidad angular es una medida de la velocidad de rotación.

¿A qué velocidad debe salir un satélite para vencer la gravedad terreste y escaparse de ella?

Concept of Uniform Rectilinear Motion

Concept of Uniformly Accelerated Rectilinear Motion. What is a uniformly accelerated movement?

Units of measurement indicate what is being measured. The number which precedes the unit of measurement indicates how much it measures.

What is a uniform circular movement?

Acceleration in a uniform circular movement

Types of spherical mirrors. spherical mirror is a reflecting surface which could be formed like a section of a sphere separated from the rest by a plane. There are two types of spherical mirrors: concave and convex.

Concept of twins paradox
