小明拿一个远视眼镜放在凸透镜前,光屏上出现烛焰清晰的像,如图所示。

若拿走远视眼镜则烛焰的像变得模糊。

下列操作能使光屏上重新得到清晰像的是A.将光屏适当靠近凸透镜 B.将蜡烛适当靠近凸透镜C.将光屏和蜡烛适当靠近凸透镜 D.将光屏或蜡烛适当远离凸透镜4.下图中描述的现象属于光的反射的是5.常见的视力缺陷有近视和远视.如图所示是一位视力缺陷者的眼球成像示意图,他的视力缺陷类型及矫正视力应该配戴的透镜种类是A.远视眼,凸透镜B.远视眼,凹透镜C.近视眼,凸透镜D.近视眼,凹透镜A.日偏食 D.雨后彩虹C.湖边夜景B.钢笔错位图16.如图所示,MN是凸透镜的主光轴,P、Q、S是在主光轴上顺次的三个位置。

把一物点放在P处,像成在Q处;如把该物点放在Q处,凸透镜位置不变,像成在S处。

则可以判断凸透镜的位置应该在:A.P的左边 B.PQ之间C.QS之间 D.S的右边7.眼睛是心灵的窗户,关于眼睛及其视力矫正,下列说法中正确的是 ( )A.眼睛的晶状体相当于凹透镜B.物体通过晶状体所成的像是虚像C.远视眼看不清近处景物,是因为景物的像落在视网膜的前方D.矫正近视眼所配戴的眼镜镜片是凹透镜8.当光从一种介质射入另一种介质时,下列说法中正确的是A.折射角大于入射角 B.折射角小于入射角C.折射角等于入射角 D.以上情况都有可能9.晚上,在桌面上铺一张白纸,把一块平面镜平放在白纸上,让手电筒的光正对着平面镜照射,如图所示,则从侧面看去()A.白纸是暗的,镜子是亮的 B.白纸和镜子都是暗的C. 白纸是亮的,镜子是暗的D. 白纸和镜子都是亮的10.、凸透镜、凹透镜和平面镜中能会聚太阳光的是__________,光从空气斜射入水中,折射角_______入射角。
