折射定律是重要的运动规律。演示和验证折射定律的方法很多,如改变宏观粒子的运动速率,可以观察粒子的“折射”;利用低频率振子在水波槽中观察水面波的“折射”;光具盘中的半圆形玻璃砖,配以氦氖激光器可以精确地验证折射定律,但造价很高。正是由于受到仪器设备的限制,在中学阶段要想精确的验证折射定律,变得比较困难。 The law of refraction is an important law of motion. There are many ways to demonstrate and verify the law of refraction, such as changing the motion rate of macroscopic particles, observing the “refraction” of particles; using low-frequency transducers to observe the “refractions” of the surface waves in a wave bath; semicircular glass bricks in optical discs The helium-neon laser can accurately verify the law of refraction, but its cost is high. It is because of the limitations of equipment and equipment that it is difficult to accurately verify the law of refraction in the secondary school.
