Description
Technical field
The present invention relates to a kind of teaching aid, specifically a kind of high school physics wave optics demonstrator.
Background technology
With the propagation of Research on fluctuation theory light and the optical branching of light-matter interaction.The 17th century, R. Hookes and C.
Huygens has founded the eave theory of light.Huygens once using wavefront concept correctly explain the reflection law of light, the law of refraction and
Birefringent phenomenon in crystal.No matter theoretical wave optics is or application all occupies an important position in physics.Particle is in light
Under the action of field or other alternating electric fields, the dipole of vibration is generated, subwave is sent out.With the absorption of Mingguang City for such model,
The transmitting of phenomena such as dispersion, scattering, magneto-optic, electric light or even light is also the content of general wave optics.
Dynamic optics is very important component part in optics, content include the interference of light, the diffraction of light, light polarization
Deng no matter theoretical or apply and all occupied an important position in physics.Particle under the action of light field or other alternating electric fields,
The dipole for forming oscillation, sends out subwave.Utilize the dispersion, absorption, scattering of Mingguang City, magneto-optic effect, electric light for this viewpoint
The transmitting of phenomena such as effect or even light is also the content of general wave optics.EM theory is applied to crystal and claims crystal optics.
The wavelength of light wave in a vacuum is about（3.9~7.6）× 10-5cm, general barrier or hole are all much larger than this, thus logical
Often all show the straightline propagation phenomenon of light extraction.This period, it has also been found that some optics related with the fluctuation of light are existing
As, for example, F.M. Grimaldis find first light meet barrier when will deviate from straightline propagation, he is named as this phenomenon " to spread out
It penetrates ".Hooke and R. Boyle, Roberts observe the interference phenomenon for being now referred to as Newton's ring respectively.These find that becoming wave optics develops
The starting point of history.Between more than 100 years after the 17th century, the corpuscular theory of light（Light-exposed duality）It dominates always, eave theory
It is not then that most people receives, after entering for 19th century, the wave theory of light is just rapidly developed.
Now in our high school physics, the fluctuation knowledge for learning light is needed, in learning process, teacher often uses
Wave optics demonstrator come the diffraction of interference, light to light, light polarization phenomena such as demonstrate, present optical demonstration instrument knot
Structure is relatively fixed, has a single function, inconvenient for use, adjusts trouble, cannot meet present requirement.
