[題目]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)
[瓶頸] (寫寫自己的想法,方便大家為你解答)
我覺得題目的意思是0.025是中央亮帶的寬度(2λL/a)
經由換算之後我算出來的答案是最小要1.6mm可是答案給的是0.98mm
不知道我是不是有算錯
謝謝~
