Portable optical reflection demonstrator

Abstract

The invention discloses a portable optical reflection demonstrator, and belongs to the field of physical teaching tools. The portable optical reflection demonstrator comprises a bottom plate, whereina vertical panel is fixed to the bottom plate; a horizontally arranged reflector, a semicircular light-shading hood with a downward opening, and a semicircular slideway with a downward opening are sequentially inlaid and mounted from bottom to top on the front surface of the vertical panel; the opening end of the semicircular light-shading hood is tightly clung to the reflector; the semicircular slideway and the semicircular light-shading hood are concentrically arranged; a plurality of light-transmitting strip-shaped holes are uniformly formed in the semicircular light-shading hood; first scale lines in the forward direction are arranged beside the light-transmitting strip-shaped holes; second scale lines in the forward direction are arranged on the reflector and at the circular center ofthe semicircular light-shading hood; circumferential radian scale lines are arranged on the vertical panel and around the circular center of the semicircular light-shading hood; a light source mechanism is connected into the semicircular slideway in a sliding manner. Through arrangement of the light source mechanism and the semicircular slideway, quick and intuitive demonstration of a reflectinglight path is achieved, and the learning interest of students is improved.

Description

Technical field [0001] The invention belongs to the field of physics teaching appliances, and particularly relates to a portable optical reflection demonstration instrument. Background technique [0002] At present, in middle school physics teaching, when teaching optics courses, especially for students who are exposed to learning light reflection and other related knowledge for the first time, students feel abstract, learning is more difficult, and there is nothing to verify whether the theory in the book is Correctly, if it is possible to demonstrate the laws of optical reflection, it can increase students' understanding and increase their divergent thinking. However, there is currently a lack of such a reflection demonstration device that can carry light with the classroom. [0003] Chinese patent CN106228877A discloses a light reflection teaching demonstration device, but its structure is relatively complicated, the operation is inconvenient, and it cannot be verified that the ...

Problems solved by technology

[0002] At present, in middle school physics teaching, when teaching optics, especially for students who are first exposed to relevant knowledge such as the reflection of light, students feel abstract, and it is difficult to learn, and there is nothing to verify whether the theory in the book is correct or not. Correct, if the law of optical reflection can be demonstrated, it will increase students' understanding and divergent thinking. However, there is currently a lack of such a reflection demonstration device that can carry light in class

[0003] Chinese patent CN106228877A discloses a light reflection teaching demonstration device, but its structure is relatively complicated, the operation is inconvenient, and it cannot be verified that the reflected light and the incident light are on the same plane, and the optical path is reversible, which is not perfect enough
