Description

Kaleidoscope principle presentation device

Technical Field

The utility model relates to the technical field of science popularization teaching aids, in particular to a kaleidoscope principle demonstration device.

Background

The kaleidoscope pattern is formed by reflecting the kaleidoscope by a glass mirror. The three-side glass mirror is a triangular prism, and glass fragments with various colors are placed at one end of the three-side glass mirror, and the fragments are reflected by the three-side glass mirror to form symmetrical patterns which look like flowers blooming like flowers.

The principle of the kaleidoscope lies in the reflection of light, and the mirror images by the reflection of light, so that the imaging principle is mastered by ancient people in ancient times in China. The ancient book "Zhuang Zi" has a statement of "identifying water", i.e. the mirror is used as the static water. The real kaleidoscope toy was said to be invented in 1816 by the scotland physicist mawei brewster jazz, and the toy was available for the long time in our country, and is innovative to produce a plurality of novel kaleidoscope.

At present, the existing kaleidoscope display modes are divided into two types: one is a commercially marketed kaleidoscope: the object with bright color is placed at one end of the cylinder, the prism is placed in the middle of the cylinder, the other end of the cylinder is sealed by the glass with the opening, and the symmetrical beautiful image can be observed by looking at the opening. It is also obvious that the participants can only see the phenomenon, cannot see the specific structure inside, and even have no optical principle involved inside.

The other is experimental demonstration: the mirror surface and the pattern related to the kaleidoscope are separated and combined manually. And the demonstration and the principle explanation are carried out by matching with the personnel such as teachers, parents and the like. But with certain difficulties. For the younger participants, the specific phenomenon cannot be intuitively felt.

The following table is summarized:

it can be seen that the existing device approaches all have their own drawbacks and deficiencies. In view of the above, how to let pupils or preschool children actively and happily participate in the related science popularization activities is a problem to be solved at present.
