    氮放电管发出的光垂直照射到某光栅上, 测得波长[tex=5.429x1.214]wacB2ckJHjFg/rzvTKB4QwF8iKtwuOrIAFydxWNUk+cAgjnH6MZtCp2CpsB1/Knd[/tex] 的谱线的衍射角为[tex=2.429x1.214]ZgHCLdC+mFB4Qsb7x2w4NA==[/tex]如果在同样[tex=0.714x1.0]G0EINCSU/4flqLNUikAogg==[/tex] 角处出现波长 [tex=5.429x1.214]pQMIIiv1lyF/JtH93/xwSzDaxN1/Dy4wfyo6KFOCwS0ST7Cq+BLx+uFD+41hFpvn[/tex] 的更高级次的谱线, 那么光栅常数最小是多少?
