问题 选择题

下列现象中,属于光的反射的是(  )

A.人在阳光下形成的影子

B.在池边,池水看起来变浅了

C.桥在平静湖水中的倒影

D.透过树叶上的露珠,看到放大的叶脉

答案

A、影子的形成说明光是沿直线传播的,由于光的直线传播,被物体挡住后,物体后面就会呈现出阴影区域,就是影子,故与题意不符;

B、从水中反射的光从水中斜射入空气中时,发生折射,折射光线远离法线,当人逆着折射光线的方向看时,看到的是池水比实际位置偏高,即池水变浅了,故与题意不符;

C、平静湖面上桥的倒影,属于平面镜成像,是由于光的反射形成的,符合题意.

D、透过树叶上的露珠看叶脉,属于凸透镜成像,是由于光的折射形成的.故本选项不符合题意.

故选C.
