WO 2.6

Principle

By carrying out this experiment using transmission gratings with largely differing grating constants, the students should gain an understanding of how these affect the interference pattern. Establishing the wavelength ? of light filtered with the ...

INTERFERENCIAS DE LA LUZ

Principle

By dividing up the wave-front of a beam of light at the Fresnel mirror and the Fresnel biprism, interference is produced. The wavelength is determined from the interference patterns.

Tasks

Determination of the wavelength of light by interferen ...

ANILLOS DE NEWTON

Principle

In a Newton's rings apparatus, monochromatic light interferes in the thin film of air between the slightly convex lens and a plane glass plate. The wavelengths are determined from the radii of the interference rings.

Tasks

Using the Newton's r ...

Newton's rings with optical base plate

Principle

The air wedge formed between slightly convex lens and a plane glass plate (Newton's colour glass) is used to cause interference of monochromatic light. The wavelength is determined from the radii of the interference rings.

Tasks

The diameters ...

DETERMINACION DE LA ZONA DE FRESNEL / ZONA DE PLACA

Principle

A zone plate is illuminated with parallel laser light. The focal points of several orders of the zone plate are projected on a ground glass screen.

Tasks

1. The laser beam must be widened so that the zone plate is well illuminated. It must ...

COHERENCIA Y ANCHO DE LINEAS ESPECTR.C.INTERFER.DE MICHELSON

Principle

The wavelengths and the corresponding lengths of coherence of the green spectral lines of an extreme high pressure Hg vapour lamp are determined by means of a Michelson interferometer. Different double slit combinations are illuminated to verify the coherence condit ...

INDICE DE REFRA. DEL AIRE Y CO2 CON INTERFEROM. DE MICHELSON

Principle

A measurement cuvette set in the beam path of a Michelson interferometer can be evacuated or filled with CO2. The refraction indexes of air or CO2 are determined through the assessed modification of the interference pattern.

Multiple slits which all have the same width and the same distance among each other, as well as transmission grids with different grid constants, are submitted to laser light. The corresponding diffraction patterns are measured according to their position and intens ...

INTENSIDAD DE DIFRACCION EN UN RENDIJA SIMPLE Y DOBLE

Principle

Slit and double slit systems are illuminated with laser light. The corresponding diffraction patterns are measured by means of a photodiode which can be shifted, as a function of location and intensity.

Tasks

1. Determination of the ...
