Abstract
The utility model relates to a straight line propagation's device is followed to demonstration light. The device including receiving screen, torch, wire and a plurality of plastic sheet, a plurality of plastic sheets on set up the same aperture in position, receipt screen and a plurality of plastic sheet follow the inline in proper order, a plurality of plastic sheet lower extremes for the height -adjustable frame of reducing expenditure. The utility model discloses simple structure, convenient, the easy student of demonstration understand, the cost of manufacture is hanged down, can be used repeatedly.
Description
Technical field
The utility model relates to a kind of optical demo equipment, particularly relates to a kind of device demonstrated light and linearly propagate.
Background technology
At present, the most complex structure of existing optical demo equipment, production cost are low, and demonstrating effect is directly perceived not, and student is difficult to understand.
Utility model content
In order to overcome the above problems, the utility model provides that a kind of structure is simple, demonstration is convenient, be easy to the device that student understands, low, the repeatedly used demonstration light of cost of manufacture is linearly propagated.
The technical solution of the utility model is: described device comprises reception optical screen, torch, tinsel and some plastic sheets, described some plastic sheets offer the identical aperture in position, described reception optical screen and some plastic sheets linearly arrange successively, and described some plastic sheet lower ends are height adjustable support.
The utility model structure is simple, demonstration is convenient, be easy to that student understands, cost of manufacture is low, can Reusability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is receive optical screen, and 2 is plastic sheets, and 3 is apertures, and 4 is height adjustable support.
Embodiment
A kind of device demonstrated light and linearly propagate, described device comprises reception optical screen 1, torch, tinsel and three plastic sheets 2, three described plastic sheet 2 lower ends are respectively height adjustable support 4, three described plastic sheets 2 offer the identical aperture in position 3, described reception optical screen 1 and three plastic sheets 2 linearly arrange successively, by tinsel successively through the aperture 3 on three plastic sheets 2, guarantee that three apertures 3 are at sustained height, tinsel is extracted out, the aperture 3 on first plastic sheet 2 is aimed at torch, finally hot spot can be shown on reception optical screen 1, then second plastic sheet 2 is raised or reduce, the aperture 3 on first plastic sheet 2 is aimed at again with torch, now receive on optical screen 1 and can not show hot spot, obtain the conclusion that bright dipping is linearly propagated.
Claims (1)
1. the device demonstrated light and linearly propagate, it is characterized in that: described device comprises reception optical screen, torch, tinsel and some plastic sheets, described some plastic sheets offer the identical aperture in position, described reception optical screen and some plastic sheets linearly arrange successively, and described some plastic sheet lower ends are height adjustable support.
