| Abstract: | The range of prism angle in the experiment of measuring the refractive index of liquid by glancing incidence is analyzed.A method of improving the visibility of the half-shadow field is put forward.At the same time,the influence of light position and prism selection on the visibility of separation line in the half-shadow field is discussed;finally the selection scheme of ordinary prism is obtained in the experiment. |
