题目:

小明利用如图所示的实验装置,进行“探究光的反射规律”的实验.

试验次数入射角反射角
130°30°
240°40°
350°50°
(1)使光线以不同角度入射进行实验,测量结果如下表所示.由此可得:在反射现象中,反射角______入射角.

(2)将一束光贴着纸板A沿EO射到0点,若将纸板B向前或向后折,目的是探究反射光线与入射光线是否在______内,此时,在纸板B上______(填“能”或“不能”)看到反射光线.

(3)若将一束光贴着纸板B沿F0射到O点,光将沿图中的______方向射出.

(4)实验中,小明无意中看到自己在平面镜中的像,那么,镜中的像是正立、______的______像.
