(1)如图1是用双缝干涉测光的波长的实验设备示意图.

Ⅰ.图1中①是光源,⑤是光屏,它们之间的②③④依次是______、______和______.(每空1分)

Ⅱ.已知双缝与屏的距离L,双缝间距d.用测量头来测量亮纹中心的距离.测量头由分划板、目镜、手轮等构成,转动手轮,使分划板左右移动,让分划板的中心刻线对准亮纹的中心(如图2(乙)所示),记下此时手轮上的读数,转动测量头,使分划板中心刻线对准另一条亮纹的中心,记下此时手轮上的读数.

(2)分划板的中心刻线分别对准第1条和第4条亮纹的中心时,手轮上的读数如图2(丙)所示,则对准第4条时读数x2=_______mm(允许误差)

(3)写出计算波长λ的表达式,λ=______(用x1、x2、L、d表示,不用计算).
