Abstract

The utility model discloses a fork-type water wave interference demonstration instrument, comprising a transparent water trough, a light source arranged below the transparent water trough for illuminating the transparent water trough, and a projector reflecting mirror arranged above the transparent water trough for receiving the light from the light source, wherein the transparent water trough is equipped with a water wave interference generation device; the fork-type water wave interference demonstration instrument is characterized in that the water wave interference generation device comprises a cylinder, a push rod of the cylinder is articulated with a fork handle of a fork, the middle part of the fork is articulated with the transparent water trough, left and right tips of the fork are positioned above the horizontal plane of the transparent water trough and positioned on the same horizontal plane; and when the push rod of the cylinder pushes the fork handle of the fork, the left and right tips of the fork stretch into water simultaneously. The fork-type water wave interference demonstration instrument has the remarkable effect that of the instrument can demonstrate water wave interference in class, realizes the effect of water wave interference in classroom and enhances the teaching quality.

Description

V shape ripples interference demonstration instrument

Technical field

The utility model belongs to teaching instrument and equipment, relates in particular to the V shape 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 V shape 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 V shape 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 cylinder, are hinged with the fork handle of fork on the push rod of this cylinder, and the middle part of this fork and transparent tank are hinged, and the left and right prong of fork is positioned at the top of described transparent tank surface level, and left and right prong is positioned on the same surface level;

When the push rod of cylinder promoted the fork handle of fork, left and right prong stretched into the water surface simultaneously.

Remarkable result of the present utility model is: a kind of V shape 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.

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 V shape 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, it is characterized in that:

Described ripples interfere generating means to comprise cylinder 4, are hinged with the fork handle of fork 5 on the push rod of this cylinder 4, and the middle part of this fork 5 and transparent tank 1 are hinged, the left and right prong 5a of

fork

5,5b is positioned at the top of described transparent tank 1 surface level, and left and right prong 5a, and 5b is positioned on the same surface level;

When the push rod of cylinder 4 promotes the fork handle of fork 5, left and right prong 5a, 5b stretches into the water surface simultaneously.
