Abstract
The purpose of a convex mirror imaging device of the utility model is to provide a convex mirror imaging teaching aid. When an optical experiment is carried out, the relation between focal length size and imaging proportion can be clearly demonstrated. The convex mirror imaging teaching aid of the utility model is composed of a bottom seat, a guideway on the bottom seat, a convex mirror and a candle on the guideway and a white board on the bottom seat. The utility model is characterized in that scales are marked below the guideway of the bottom seat, and the longitudinal direction of the white board is marked with the scales. When the utility model is used, the size of focal length and imaging size can be read out through the scales to make the experiment more systematic.
Description
Technical field
The utility model relates to a kind of teaching aid of convex lens imaging.
Background technology
Use the light refraction principle that the convex lens imaging device introduces to the student convex lens in the physics teaching in junior middle school now widely, but, make education experiment can accurately not verify the relation of focal length and imaging size owing to there is not the sign of distance in the existing teaching aid.
Summary of the invention
The purpose of a kind of convex lens imaging device of the utility model provides a kind of teaching aid of convex lens imaging, makes it can clearly demonstrate when carrying out Experiments of Optics the relation of focal length size and imaging ratio.A kind of convex lens imaging of the utility model teaching aid is made up of the guide rail on base, the base, convex lens on the guide rail and the blank on candle and the base, it is characterized in that indicating scale below the guide rail of base, vertically indicates scale at blank.The utility model size of focal length and size of imaging in use can be read by scale, makes the more system of testing.
Description of drawings
Figure one is the structural representation of a kind of convex lens imaging device of the utility model,
Embodiment
Shown in figure one, a kind of convex lens imaging of the utility model teaching aid indicates scale 2 below the guide rail of base 1, vertically indicates scale 4 at blank 3.
Claims (1)
1, a kind of convex lens imaging of the utility model teaching aid is made up of the guide rail on base, the base, convex lens on the guide rail and the blank on candle and the base, it is characterized in that indicating scale below the guide rail of base, vertically indicates scale at blank.
