| Abstract: | Measuring the period of the spring oscillator on the air-cushion guide is an important experiment in middle school physics.The experiment generally uses a photoelectric gate and a light-block to measure the period of the spring oscillator.The experimental method is relatively simple,and the experiment process is prone to errors.The article provides several calculation methods for the spring oscillator period under the combination of different photogates and light barriers,solves the problems in the experimental measurement,cultivates the students'divergent thinking,and exercises the students'ability to solve problems. |

| Keywords: | photogate light block spring oscillator period measurement scheme |
