图是探究平面镜成像的实验装置,关于这个实验:

(1)应选择            来研究平面镜成像特点(填“平面镜”或“平板玻璃”);

(2)观察像时,会发现两个几乎重叠的像,这是___           __造成的;

(3)如果在像A’的位置放一个光屏,在光屏上____承接到像A’(填“能"或“不能”),说明平面镜成的像是_____像;

(4)如果将蜡烛向靠近镜面的方向移动,那么像的大小将______(填“变大”、“变小”或“不变”)。

答案

(1)平板玻璃;(2)平板玻璃的两个反射面成像;(3)不能、虚;(4)不变;

题目分析::(1)玻璃板既能反光,又能透光,虽然成像不如平面镜清晰,

但玻璃板透光性好,能在观察到A蜡烛像的同时,也能观察到B蜡烛,便于确定像的位置和大小问题.而选择平面镜就无法观察后面的蜡烛了,所以是平板玻璃.

(2)平板玻璃有两个面,并且都会将蜡烛的像反射回来,这时便会有两个重叠的像,

所以是由平板玻璃的两个反射面成像.

(3)平面镜成的像是光的反向延长线相交而成,如果在像A′位置放一个光屏,光屏无法承接像,所以此时成虚像.

(4)根据平面镜成像特点知:像的大小与物体等大,所以无论如何移动蜡烛,像的大小都不会变.

点评:本题主要考查学生对探究平面镜成像的实验的掌握程度。实验时应用玻璃板代替平面镜,便于观察和确定像的位置,玻璃板不宜太厚,防止折射成像的干扰。玻璃板要竖直放置,与桌面垂直。

Though England was on the whole prosperous and hopeful, though by comparison with her neighbors she enjoyed internal peace, she could not evade the fact that the world of which she formed a part was torn by hatred and strife as fierce as any in human history. Men were still for from recognizing that two religions could exist side by side in the same society; they believed that the toleration of another religion different from their own. And hence necessarily false, must inevitably destroy such a society and bring the souls of all its members into danger of hell. So the struggle went on with increasing fury within each nation to impose a single creed upon every subject, and within the general society of Christendom to impose it upon every nation. In England the Reformers, or Protestants, aided by the power of the Crown, had at this stage triumphed, but over Europe as a whole Rome was beginning to recover some of the ground it had lost after Martin Luther’s revolt in the earlier part of the century. It did this in two ways, by the activities of its missionaries, as in parts of Germany, or by the military might of the Catholic Powers, as in the Low Countries, where the Dutch provinces were sometimes near their last extremity under the pressure of Spanish arms. Against England, the most important of all the Protestant nations to reconquer, military might was not yet possible because the Catholic Powers were too occupied and divided: and so, in the 1570’s Rome bent her efforts, as she had done a thousand years before in the days of Saint Augustine, to win England back by means of her missionaries.

These were young Englishmen who had either never given up the old faith, or having done so, had returned to it and felt called to become priests. There being, of course, no Catholic seminaries left in England, they went abroad, at first quite easily, later with difficulty and danger, to study in the English colleges at Douai or Rome: the former established for the training of ordinary or secular clergy, the other for the member of the Society of Jesus, commonly known as Jesuits, a new Order established by St, Ignatius Loyola same thirty years before. The seculars came first; they achieved a success which even the most eager could hardly have expected. Cool-minded and well-informed men, like Cecil, had long surmised that the conversion of the English people to Protestantism was for from complete; many—Cecil thought even the majority—had conformed out of fear, self-interest or—possibly the commonest reason of all—sheer bewilderment at the rapid changes in doctrine and forms of worship imposed on them in so short a time. Thus it happened that the missionaries found a welcome, not only with the families who had secretly offered them hospitality if they came, but with many others whom their first hosts invited to meet them or passed them on to. They would land at the ports in disguise, as merchants, courtiers or what not, professing some plausible business in the country, and make by devious may for their first house of refuge. There they would administer the Sacraments and preach to the house holds and to such of the neighbors as their hosts trusted and presently go on to some other locality to which they were directed or from which they received a call.
