Embodiment Construction

[0028] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] The disadvantage of the traditional Young's teaching instrument is that the lens inside needs to be disassembled and adjusted after each test. Because each test requires a different spacing between the lenses. The technical solution of the present invention regulates the distance between lenses by adding a magnetic field, which avoids the trouble of disassembly; the technical solution of the present invention also protects the method of controlling the distance with a magnetic field.

[0030] According to an embodiment of the present invention, such as figure 1 , figure 2 and image 3 As shown, based on a new type of magnetically controlled intelligent co...

Abstract

The invention discloses a double-slit device capable of being regulated. The double-slit device capable of being regulated comprises an electromagnetic structure which is arranged in a symmetrical mode and can form a magnetic field loop and a double-slit structure arranged in the center of the electromagnetic structure. By means of the double-slit device capable of being regulated, the defects that in the prior art, the horizontal positions of a lighting system, a double-slit system and an observation system need to be assembled and disassembled and adjusted again when multiple experiments are conducted, the difficulty in assembly and disassembly is large, and time is wasted can be overcome, and the double-slit device capable of being regulated has the advantages of being simple in structure, low in assembly and disassembly difficulty and capable of saving time.

Description

technical field [0001] The invention relates to the technical field of physics teaching instruments, in particular to an adjustable double-slit device. Background technique [0002] The double-slit interference experiment is one of the basic experiments to understand the characteristics of light in high school physics teaching, and it is also the basis of modern optics. Its principle is mainly to divide the light emitted by a line source into two coherent light waves through two parallel slits that are close together. When two coherent light waves meet in space, there will be a phenomenon of mutual strengthening or mutual weakening, that is, at the place where the optical path difference is equal to zero or equal to an integer multiple of the wavelength, they will strengthen each other to form a bright spot; at the place where the optical path difference is equal to an odd multiple of half the wavelength , cancel each other out to form a dark spot. The main factors affecti...
