I worked so hard because I had a great   4   — one day, I would be the first   5   person to win the Nobel Prize in physics. Later on, I found physics at school too easy for me.

如图所示,是小明在“探究平面镜成像的特点”的活动中所选用的器材和活动过程。

(1)在探究活动中对玻璃板放置的要求是____,

(2)选择蜡烛A和B的要求是____;

(3)如果在图甲中蜡烛像的位置上放一张白纸板做屏幕,则白纸板上将____(填写 “有 ”或“没有”)蜡烛的像;此现象说明____

(4)把蜡烛B放到蜡烛A像的位置上,将会看到图丙所示的现象。这说明____。

(5)实验中将蜡烛逐渐远离玻璃板时,蜡烛所成像的大小____(选填“变大”、  或“变小”或“不变”),实验中哪个现象能证明你的观点?____  

(6)小崔想还有没有其他方法可以测量像距?

于是小崔把刻度尺和蜡烛并在一起,读出了蜡烛的长度,又在平面镜里看到了蜡烛和刻度尺的像,就可以透过平面镜读出蜡烛像的大小。以上方案是否可行,请你对其进行评价。
