Description
Technical field
The invention belongs to teaching demonstration appliance technology, in particular to the interference demonstration device of a kind of wave.
Background technique
" interference of wave and diffraction " is an important content of courses of Middle School Physics.In practice of imparting knowledge to students, teacher is mainly taken
Based on principle is lectured, the teaching method supplemented by video display.Due to the shortage of experimental demonstration device, rarely have teacher to do true class
Hall experimental demonstration.Chinese patent literature CN 101059917A discloses interference and the diffraction experimental device of a kind of wave, the device packet
Sink, elastic sheet and wave source are included, the both ends of elastic sheet are fixed on the edge of sink, one is fixed with below elastic sheet
Or more than one wave source.The program is fixed on the edge of sink due to the both ends of elastic sheet, and jitter effect will not be obvious, water
Telling on for wave is unobvious, and experimental phenomena is not good enough.Applicant has found, little wind in a chance opportunity at an arm of lake
Power, some regions between 2 blocks of stones in lake produce apparent interference phenomenon.It exchanges, test, change with counselor later
Into ultimately forming this programme.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of interference demonstration devices of wave, can generate
Obvious interference phenomenon.
To achieve the goals above, technical scheme is as follows: the interference demonstration device of wave, including sink, described
Sink includes inlet and outlet, and at least two barrier is provided in sink, and barrier is set side by side in the same side of water inlet
It sets, the height of barrier is greater than the height of sink.
As an improvement, the barrier with sink in water surface intersection sectional area be greater than 10CM2。
As an improvement, the spacing between barrier barrier adjacent thereto is 2CM~8CM.
As an improvement, the spacing between the barrier and the edge of the sink is greater than 4CM.
As an improvement, the barrier is cylindrical body.
As a further improvement, the rectangular triangle of sink, water outlet are located at the right angle of sink, water inlet is located at
At one of acute angle of sink.
As a further improvement, the sink is provided with guide plate in water inlet.
As further improving, it is provided with water pump in the sink, is connected between inlet and outlet by conduit, water
Clear water in sink is imported water inlet after water outlet extraction by pump.
The present invention simple, simple for production, experimental phenomena clear advantage with structure is suitable for teaching classroom demonstration.
Detailed description of the invention
Fig. 1 is top view of the invention.
In figure: 1, sink；11, water inlet；12, water outlet；2, barrier；3, guide plate；4, water pump；5, conduit.
Specific embodiment
Embodiment 1
As shown in Figure 1, the interference demonstration device of wave of the present invention, including sink 1, sink 1 are fixed on a bracket (figure
In be not shown) on, the rectangular triangle of sink 1, the water outlet 12 of sink 1 is located at the right angle of sink 1, and water inlet 11 is located at water
At one of acute angle of slot 1.
It is provided at least two barrier 2 in sink 1, there are 3 barriers 2 in the present embodiment, barrier 2 is in water inlet 11
The same side be arranged side by side.Barrier 2 is located at the intermediate region of sink 1, and barrier 2 is cylindrical body.The height of barrier 2 is greater than
The height of sink 1.Barrier 2 with sink 1 in water surface intersection sectional area be greater than 10CM2, sectional area is too small, tests
Phenomenon is not obvious enough.Spacing between adjacent barrier 2 is 2CM~8CM.Spacing between barrier 2 and the edge of sink 1
Greater than 4CM.
It is provided with water pump 4 in sink 1, is connected between water inlet 11 and water outlet 12 by conduit 5, water pump 4 will be in sink 1
Clear water is after the extraction of water outlet 12 through importing water inlet 11 by conduit 5.Sink 1 is provided with guide plate 3 at water inlet 11, guidance
Piece 3 makes the clear water for importing water inlet 11 not face barrier 2 and wash away, and clear water is made to form slight rotation at barrier 2
Effect.
When experimental demonstration, water pump 4 is opened, flows the clear water in sink 1 from water inlet 11 to water outlet 12, clear water is hindering
After hindering the side of object 2 to be flowed through, while 3 barriers 2 can be hit, 2 surrounding of barrier can generate complete circular wave.This programme
Why obviously experimental phenomena can be obtained, it may be possible to due to the influence of water flow make to form around barrier 2 it is slight
Rotating Vortex reinforces the vibration of some regions, and the degree that ripples stick out is significantly greater than other regions.In Fig. 1, use
Dotted line frame outlines the position come, and the visual effect of ripple superimposed is significantly stronger than other positions.Region between adjacent barrier 2,
Although theoretically the amplitude of ripple vibration is similarly superimposed, it may be possible to due to test medium, the front of ripples
Collision make vibration is weakened, experimental phenomena be not so good as with dotted line frame outline come position it is obvious.
