某液体下有一光源,光线散射出来时在液体表面形成半径10CM的圆,已知该液体对光的折射率为1.3,请问光源在液体下多深.
设深度为X,则 折射率=sqr(圆直径平方+4x深度平方)/圆直径
即:1.3=sqr(100+4x^2)/10
13^2=100+4x^2
得 x = 8.3/2 cm,上面答案均不对

一点光源位于某液体中,其发出的光线需经过一个半径为10厘米的圆形区域离开液体表面。液体的折射率为1.3,求光源距离液体表面的高度。
我的答案是 根号下69~~貌似没选项~~

液体中有一个点光源。在液体平面上投射出一个半径10cm的圆形区域,已知液体折射率为1.3。求点光源在液体中深度。
