照相机可以记录生活中美妙的瞬间,投影仪能通过大屏幕演示精彩的画面,放大镜可以显示我们肉眼不易观察到的细微部分,这三者都离不开一个共同的部件——凸透镜．照相机、投影仪、放大镜在成像时都遵循凸透镜成像规律,但它们所成的像的大小、位置、倒正各不相同,我们通过实验探究,可以得出凸透镜 The camera can record the wonderful moments in life. The projector can demonstrate the wonderful picture through the big screen. The magnifying glass can show the subtle parts that we can’t easily observe with the naked eye. All three are inseparable from a common component - the convex lens. Cameras, projectors, and magnifiers all follow the rules of lenticular imaging when imaging. However, the size, position, and reversal of the images formed by them are all different. Through experimental exploration, we can obtain convex lenses.
