Abstract
The invention discloses a shadow change simulator. The shadow change simulator is applied to explorations of relationship between a shadow of an object and a height of the object. Exploration of physical phenomena in nature is restricted by various conditions, so that simulation can promote scientific exploration greatly. For example, the exploration of relations between a shadow of an object and the height of the object can be simulated. A parabolic orbit is erected on a flat board and a light source moves along the orbit. An object is arranged in the center of the orbit and scale is arranged on the flat board along the direction of the orbit.
Description
Technical field
The present invention is useful for the relation of probing into shadows of objects and object height.
Background technology
Probe into the nature physical phenomenon and will receive many condition restriction, bring spring if ability simulation meeting will be probed into to science.Just probing into of relation like shadow and object height can be simulated.
Summary of the invention
In order to probe into the relation of shadows of objects and object height, the present invention provides a kind of shadow to change appearance.The design that this shadow changes appearance is on flat board, to erect parabolic orbit, and light source moves at track, and object places the dull and stereotyped central authorities of track, and the direction along ng a path scale is as shown in the figure on flat board.The invention has the beneficial effects as follows, probe into the relation of shadows of objects and object height, simple in structure, easy and simple to handle.
Description of drawings
Fig. 1 changes the structural representation of appearance for shadow:
Wherein 1 is parabolic orbit, the 2nd, and light source, the 3rd, object, the 4th, scale, the 5th, dull and stereotyped.
Embodiment
Among Fig. 1, on dull and stereotyped (5), erect parabolic orbit (2), light source (2) moves at track, and object (3) places the dull and stereotyped central authorities of track, direction along ng a path scale (4) on flat board.Ruler is measured the height of object, and light source (2) impinges upon object (3) upper edge track and moves, and shadow is gone up at scale (4) and changed.
Claims (1)
1. shadow changes appearance, and it is characterized in that: on flat board, erect parabolic orbit, light source moves at track, and object places the dull and stereotyped central authorities of track, direction along ng a path scale on flat board.
