Find the diameter of the eye structure that causes a circular diffraction pattern with the first dark ring at an angle of 3.7 ° when viewed with monochromatic light of wavelength 590nm . (Typical eye structures of this type have diameters on the order of 10 μm. Also, the index of refraction of the vitreous humor is 1.336.) 我的答案 λn = λ/n = 590 nm/1.336 = 441.6168 nm sinθ = λn/a >>> a = λn/sinθ = 0.4416168*10^-6/sin3.7 = 6.83 * 10^-6 m = 6.83 μm 但答案不對 請問錯在哪裡 感謝感謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 99.25.204.89
