Fluorescencia de resonancia de sodio

Principle

Resonance fluorescence is demonstrated by illuminating a sodium vapour with white visible light. The emitted light is spectrally analyzed and shows the emission spectrum of sodium. Therefore the same atomic levels are involved in both absorption and emission.

Medición de longitudes

Principle

The students should measure length, diameter, and hole depth of various objects with a measuring tape and/or vernier caliper as possible. In doing this they should choose and use the more suitable measuring device. The results should be entered in the table as a numerical value ...

Medición de tiempos

Principle

The student should count the oscillations of a pendulum while timing them with the aid of a stopwatch. To determine the dependence of the oscillation period on  the length of the pendulum is shortened by 50% in the second part of the experiment.

Benefits

  • Real stand ...

Determinación de la masa de sólidos y líquidos

Principle

1. The students should determine the mass of solid bodies with the aid of a balance. 

2. The measurement of the mass of liquids can only be performed using a container. The students should determine the mass from the difference of two measurements.

Benefits

  • Real ...

Determinación del volumen de cuerpos regulares e irregulares

Principle

The students should determine the volume of 3 solid bodies. In doing this they should know that the cubic meter (m3) is the unit of volume and also that the term liter (l) is very common.

  1. On immersion of a solid body in a graduated cylinder, the difference of the ...

Determinación de la densidad de sólidos

Principle

In the previous experiments on determination of mass and volume (ME 1.3 and ME 1.4), the students have learned that both metal columns have the same volume but different masses. They know that the two objects consist of iron and aluminium. Obviously, the two materials ...

Determinación de la densidad de líquidos

Principle

In the determination of the density of solids in Experiment ME 1.5, the density was determined as the quotient of mass and volume from a weighing to determine the mass and measurement of volume by different methods. As a prerequisite for this experiment, it was assumed that the ...

Fuerza y fuerza antagonista

Principle

1. The students should learn with the help of the spring balance that a force on a body can only be exerted when a counterforce acts on it simultaneously.

2. Using two spring balances, the students should experimentally determine that the forces on both spring balances are ...

Fuerza por peso

Principle

The students are to determine the weight which a mass experiences in the earth's gravitational field with a spring balance. They should know that force is measured in N = kg  m∕s2 and recognize that weight is proportional to mass. The proportionality factor is ...

Peso con measureAPP



Principle

"A mass is not only inert but also heavy." Which is intended to mean that not only is a force necessary to accelerate a mass, but also that each mass in the earth's gravitional field experiences a force, the force of weight. The force of weight is to be measured ...

Flexión de una lámina elástica

Principle

  1. The students should investigate the behaviour of a leaf spring under load, make a graph of the measuring results and - most importantly - determine the spring constant D.
  2. In the course of the same experiment, the (tractive) force should be determined at different angles for ...

Flexión de una lámina elástica con measureAPP

Principle

Leaf springs are thin metal plates that are elastically deformed under load: When a force is applied to a
leaf spring, then it is subject to deformation. A characteristic of such an elastic deformation is that the
original shape is re-formed when the force is no longer active. In ...
