在高中物理“显示微小形变”和“卡文迪许扭秤装置”的两个实验中,应用了光学放大法.这一方法是将需要测量的微小量或观察到的微小效应,应用光学器件按一定的规律将它们“放大”显示出来,以便于更准确地观察和测量.根据“光学放大法”所应用的物理规律,可以分为直射放大、反射 Optical magnification was used in two experiments in high school physics “show small deformations” and “Cavendish twisting balances.” This method uses small amounts of microscopic or microscopic effects to be measured, applying optics According to a certain rule, they are “magnified” displayed in order to facilitate more accurate observation and measurement.According to the “optical amplification method” applied to the laws of physics, can be divided into direct amplification, reflection
