[题目]A camera lens 50mm from the plane.The lens focus the light from
two distant point sources so that the centers of their diffraction
patterns are separated by 0.025mm,Find the smallest diameter of lens
aperture in mm that allows these two images to be resolved in the
visible wavelength range(400nm<λ<700nm)
[瓶颈] (写写自己的想法，方便大家为你解答)
我觉得题目的意思是0.025是中央亮带的宽度(2λL/a)
经由换算之後我算出来的答案是最小要1.6mm可是答案给的是0.98mm
不知道我是不是有算错
谢谢~
