成像儀的製作

 製作材料:圓形三合板一塊(半徑10釐米)、平面鏡兩片(8釐米×5釐米)、量角器一塊、粗鐵絲一段(長6釐米)、門窗小合頁一個(高5釐米左右)、502超級膠水。

  製作方法:

  1、在量角器的圓心和圓形三合板的圓心上各鑽一個小孔;

  2、把小合頁中的小鐵棒抽掉,用粗鐵絲依次穿過量角器圓心、小合頁、三合板圓心,即用粗鐵絲做轉軸;

  3、用502膠水將兩片平面鏡分別粘貼在合頁上,注意:兩鏡面要相向;

  4、用膠水把其中一面鏡片的

  上邊粘在量角器的零刻度線上,下邊粘在三合板上,成像儀就做好了。

  使用方法:在兩片平面鏡之間的三合板上放上一個小物體,轉動另一片鏡面,變換兩片鏡面夾角的度數,可看到鏡中小物體不同數目的成像。細心觀察的同學也許還可以發現其中的成像規律。

  注意:使用502超級膠水必須特別小心,最好由大人為你粘貼
