高中物理第三册第179節(照相術)及初中物理下册第24節(照相機)所講的顯像法,都需要在暗室裏進行,白天在課室裏是無法演示的。現在我將個人在課室裏演示顯像的方法介紹如下,請大家指正。一、製造暗箱代替暗室:做一個木板底、紅玻璃框的暗箱,它的尺寸如圖1所示。底板的四周,應比中間稍低,並貼上黑色絨布條,以使玻璃框和底板接觸的地方不致漏光。ABEF,ADHE,BCGF,AIKJ,JLCD四面均裝上紅玻璃(若無紅玻璃,可在白玻璃上黏一層紅玻璃紙),IBLK面裝的是白玻璃。在箱子里IBLK底下做一個和IBLK同樣大小
High School Physics Volume III, Section 179 (Photography) and Junior Physics Book 24 (Camera), the imaging method, all need to be carried out in the dark room, during the day in the classroom is unable to demonstrate. Now I will personal demonstration in the classroom presentation method is as follows, please correct me. First, to create darkroom instead of darkroom: to make a wooden bottom, red glass box darkroom, its size shown in Figure 1. Surrounding the floor should be slightly lower than the middle, and black velvet sticking, so that the glass and floor contact with the place will not leak light. ABEF, ADHE, BCGF, AIKJ, JLCD are fitted with red glass on all sides (if there is no red glass, white glass can be glued to a layer of red cellophane), IBLK face loaded with white glass. IBLK in the box under the same size and IBLK
