Abstract
The utility model discloses an electromagnetic type water wave interference demonstrator, comprising a transparent water channel, a light source and a slide projector reflector, wherein the light source is arranged below the transparent water channel and illuminates the transparent water channel; the slide projector reflector is arranged above the transparent water channel and receives light from the light source; and a water wave interference generating device is installed on the transparent water channel. The electromagnetic type water wave interference demonstrator is characterized by comprising a water fetching fork; the left fork tip and the right fork tip of the water fetching fork are positioned above the water plane of the transparent water channel; the middle of the water fetching fork is hinged with the transparent water channel; a fork handle of the water fetching fork is fixedly provided with a magnetizer; an electromagnetism generator is arranged above the magnetizer; and when the electromagnetism generator sucks the fork handle of the water fetching fork, the left fork tip and the right fork tip extend into water simultaneously. The electromagnetic type water wave interference demonstrator has the obvious effects of being capable of demonstrating water wave interference in a classroom so as to introduce the water interference effect in the classroom, and improve teaching quality.
Description
Technical field
The utility model belongs to teaching instrument and equipment, relates in particular to the electromagnetic type ripples interference demonstration instrument of a kind of middle school physics demonstration.
Background technology
In learning the physics course, it is a compulsory course that ripples are interfered, and the effect that ripples are interfered is very abstract, and the student is difficult to understand its physical effect on the classroom, owing to there is not the ripples interference demonstration teaching aid of specialty, teaching efficiency is relatively poor.
The shortcoming of prior art is: on the classroom, owing to there is not the ripples interference demonstration teaching aid of specialty, the effect that ripples are interfered is very abstract, and student's indigestion influences quality of instruction.
The utility model content
The purpose of this utility model provides a kind of electromagnetic type ripples interference demonstration instrument, the ripples interference effect can be moved into the classroom, improves the quality of teaching.
For achieving the above object, the utility model is explained a kind of electromagnetic type ripples interference demonstration instrument, comprise transparent tank, and be arranged in below the transparent tank, and according to light source to transparent tank, be arranged in the slide projector reflective mirror of transparent tank top reception source light, ripples be installed on the described transparent tank interfere generating means, its key is:
Described ripples interfere generating means to comprise the fork of fetching water, this left and right prong of fetching water fork is positioned at the top of described transparent tank surface level, middle part and the transparent tank of pitching of fetching water is hinged, and the fork handle place of the fork of fetching water is fixed with magnetic conductor, and this magnetic conductor top is provided with electromagnetic generator;
When described electromagnetic generator adhesive is described fetch water the fork fork handle the time, left and right prong stretches into the water surface simultaneously.
The electromagnetic generator energising adhesive fork fork handle of fetching water, the left and right prong of the fork of fetching water hits the water surface, forms ripple.The electromagnetic generator outage, the fork fork handle of fetching water relies on deadweight to break away from electromagnetic generator, and left and right prong leaves the water surface.
Electromagnetic generator utilizes electromagnetism adhesive principle, and the principle of work as electromagnetic relay belongs to mature technology, does not repeat them here.
The line of the described left and right prong of fork of fetching water is parallel with surface level.
Remarkable result of the present utility model is: a kind of electromagnetic type ripples interference demonstration instrument simple in structure is provided, can have demonstrated ripples and interfere on the classroom, the ripples interference effect is moved into the classroom, improved quality of instruction.
Description of drawings
Fig. 1 is mounting structure figure of the present utility model;
Fig. 2 is the vertical view of transparent tank;
Fig. 3 is the side view of transparent tank.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, 2, 3, a kind of electromagnetic type ripples interference demonstration instrument, comprise transparent tank 1, and be arranged in transparent tank 1 below, and according to light source 2 to transparent tank 1, be arranged in the slide projector reflective mirror 3 of transparent tank 1 top reception light source 2 light, ripples be installed on the described transparent tank 1 interfere generating means, its key is:
Described ripples interfere generating means to comprise the fork 5 of fetching water, the left and right prong 5a of this fork 5 of fetching water, 5b is positioned at the top of described transparent tank 1 surface level, fetch water fork 5 middle part and transparent tank 1 is hinged, fork 5 the fork handle place of fetching water is fixed with magnetic conductor 6, and these magnetic conductor 6 tops are provided with electromagnetic generator 4;
When described electromagnetic generator 4 adhesives are described when fetching water fork 5 fork handle, left and right prong 5a, 5b stretches into the water surface simultaneously.
The described fork 5 left and right prong 5a that fetch water, the line of 5b is parallel with surface level.
Also electromagnetic generator 4 can be arranged on the below of fork handle, electromagnetic generator 4 energising adhesives are fetched water and are pitched 5 fork handles, the left and right prong 5a of the fork 5 of fetching water, and 5b breaks away from the water surface.Electromagnetic generator 4 outages, the fork 5 left and right prong 5a that fetch water, 5b relies on deadweight to fall into the water surface, forms ripple.
