On May 4th Youth Day, the school invited a photographer to photograph graduation photo for the students. After queuing up, the photographer found that several students were not in the box.
Test and analysis: In order to let all the students enter the camera, the image should be smaller, the image distance should be smaller and the object distance should be larger. According to the law of convex lens imaging, to make all students enter the camera, the image distance should be smaller and the object distance should be larger, so people should be still, the camera should be far away from people and the lens should be retracted.
So choose D.
Comments: The key to solve this problem is to be familiar with the relationship between object distance and image distance in convex lens imaging: as the image becomes smaller, the image distance becomes smaller and the object distance becomes larger.
