An experimental device for measuring the refractive index of glass used in high school physics

Abstract

The invention discloses an experimental device for measuring the refractive index of glass for high and middle school physics, including a base, a telescopic rods, test benches and fixing plates, thebottom of the base is provided with a leg, A placement slot is arranged in the base, a battery is installed in the placement slot, a telescopic rod is installed at the central position of the top of the base through a rotary table, and a finite position hole is uniformly distributed on the telescopic rod, a placement box is installed on the base on one side of the rotary table, an output end of the telescopic rod is installed with a test bench, and a first sliding slot is arranged in the test bench. In accordance with that present invention, a series of structures, such as telescopic rods, test benches and fixing plates. The experimental device for measuring the refractive index of glass used in high school physics is more convenient to measure and use, so that the device can not be affected by the measuring environment. The expansion rod installed on the base through the rotary table enables the device to switch the angle and the height according to the number of students at will whendisplaying. The device has strong practicability and the value is popularized and used.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to an experimental device for measuring the refractive index of glass used in high school physics. Background technique [0002] Senior high school is the abbreviation of senior high school. Middle school in my country is divided into junior high school and senior high school. Among them, high school belongs to the category of senior high school education. Senior high school is a higher education institution after the end of nine-year compulsory education in my country. Generally, it is a three-year system. In high school, physics is an important study subject. At the same time, physics is a relatively important course in high school. Because physics involves a lot, it is not limited to the content of books, but needs to be passed through experiments. To present it more intuitively, so that students can learn more physical phenomena through observation, among which the refractive ind...

Problems solved by technology

[0003] However, the current experimental device for measuring the refractive index of high school physics glass is relatively simple, which reduces the interest of high school students in physics, and the configuration is relatively simple. High school students can only simply see the refraction of light from the device. Students' knowledge cannot be expanded, because the teacher needs to show during the experiment, but because of the number of students, some students cannot watch the display more intuitively, which will easily lead to high school students' understanding of the measurement method of the refractive index. Comprehensive, thus affecting the understanding of physics. At the same time, the current experimental device for measuring the refractive index of high school physics glass is not flexible enough to switch the angle of refraction at will, which will easily affect the accuracy of the measured value.
