【摘要】 He-Ne激光器发出的激光(波长:632.8 nm)经过第一块偏振片成为线偏振光,经过第二片偏振片、放大镜(放大倍数×3)后,再垂直入射到正交的双光栅上,在接收屏上会出现衍射光斑,改变光栅在光具座上的位置,接收屏上衍射光斑的间距也相应变化,本文根据这个变化用Excel处理软件、图形和公式展现存在的实验规律,本文拓展了实验内容,找到了新的实验规律。更多还原

【Abstract】 The laser emitted by the He-Ne laser(wave:632.8 nm) pass through the first piece of polaroid and become linear polarized light,and pass through the second polaroid、magnifying glass(magnification times×3),continue to vertically pass through orthogonal double grating again,there will be the diffraction spots that appears at the receiving screen,the position of the grating was changed in the optical bench,the distance between diffraction spots were accordingly changed at the receiving screen.The Excel software processing,figures and a formula were used to show existing experimental law,it extends the experiment contents and discover a new experimental law.更多还原
