Abstract
The utility model discloses a demonstration device for the formation of wave, which belongs to a teaching aid; the utility model aims at providing a wave forming device which has simple structure, convenient operation and good demonstration effect. The utility model comprises a spring; the spring (1) is horizontally arranged on a panel (2), one end of the spring (1) is fixed and connected with the panel (2). The utility model has the advantages that the structure is simple, the operation is convenient, and the demonstration device can demonstrate the generation, the propagation, the superposition, the interference and other physical phenomena of the wave; the utility model is the ideal physics experimentation teaching aid.
Description
Technical field:
The utility model relates to a kind of physics teaching aid, relates in particular to a kind of waveform apparatus for demonstrating.
Background technology:
Ripple is a knowledge point must grasping in the physics teaching in secondary school, and its content is more abstract; At present, generally be to adopt the rope made of hemp or straw rope as easy demonstrating appliance, because the elasticity of the rope made of hemp or straw rope is relatively poor, the length of rope does not have to change substantially when shake, and and panel between friction force bigger, so the waveform duration is not long, the demonstration DeGrain.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of formation apparatus for demonstrating of ripple of simple in structure, easy to operate, good demonstration effect.
To achieve these goals, the utility model by the following technical solutions: it comprises spring; Be placed on the panel, an end of spring is fixedlyed connected with panel spring horizontal.
Compared with the prior art, the utility model is owing to adopt the rope that the spring elasticity of substitution is relatively poor, friction force is bigger, therefore waveform longer duration in presentation process, can be intuitively, the formation principle of analog wave visually, help multiple physical phenomenons such as generation that the student understands ripple, propagation, stack, interference.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: spring 1 panel 2
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: spring 1 flatly is placed on the panel 2, and an end of spring 1 is fixedlyed connected with panel 2.Because spring 1 has better elastic, flexibility and retractility, and the friction force between spring 1 and the panel 2 is less, therefore the utlity model has advantages such as energy loss is less, waveform longer duration.
Claims (1)
1. the formation apparatus for demonstrating of a ripple comprises spring; It is characterized in that: spring (1) flatly is placed on the panel (2), and an end of spring (1) is fixedlyed connected with panel (2).
