Description

A kind of polarised light apparatus for demonstrating

Technical field

The utility model belongs to science and education demonstrating appliance technical field, and in particular to a kind of polarised light apparatus for demonstrating.

Background technique

Direction of vibration is called polarization for the asymmetry of the direction of propagation, it is that shear wave is different from one of other longitudinal waves most Apparent mark, only shear wave just has polarization phenomena.Light wave is electromagnetic wave, and therefore, the direction of propagation of light wave is exactly electromagnetic wave The direction of propagation.Electric oscillation vector E and magnetic vibration vector H in light wave is vertical with spread speed v, therefore light wave is shear wave, it With polarizability, the light with polarizability is then known as polarised light.Polarizing film can make natural light become polarised light.

Emergent light can show color and be known as the phenomenon that capable of changing along with the rotation of polarizing film its color Colour developing polarization.With white light polarizing film, with the rotation of polarizing film, the brightness of emergent light, shade degree can all occur Variation.

Polarised light is very widely used in daily life, but due to its conceptual abstraction, theoretical property is strong, is optical knowledge body The difficult point of system.Current polarised light science and education demonstration majority of case is to complete in laboratory, and can not rotate freely, and is demonstrated Content is relatively simple, and the universal interest of science and education and vividness are poor, is not easy to be received by teenager, demonstrating effect is not to manage very much Think, is unfavorable for that teenager is helped relatively to be fully understood by the relevant knowledge for grasping polarised light.
