一實驗的給果如下:
雙縫間距=0.11cm
雙縫和觀測到條紋的平面的距離=98.2cm
第n道和第(n+10)道條紋的距離=0.52cm
求光的波長.

The separation between adjacent finges = w.D/a
where w is the wavelength of light used,
D is the distance between the slits and the screen,
a is the separation between slits.
Thus, separation between the n-th and (n+10) th fringes is
= 10w.D/a
hence, 0.52 = 10w x 98.2/0.11
i.e. w = 0.52x0.11/(98.2 x 10) cm

可見光(visible light)是電磁波譜中人眼可以感知的部分，可見光譜沒有精確的範圍；一般人的眼睛可以感知的電磁波的波長在400到700奈米之間，但還有一些人能夠感知到波長大約在380到780奈...
