A clear image of an object is formed on the film of a camera. As the object move

Question

A clear image of an object is formed on the film of a camera. As the object moves closer to the camera, for a clear image to still be formed on the film, what change occurs in the camera? the lens moves farther away from the film the lens moves closer to the film the lens' focal length increases the lens' focal length decreases (b) A clear image of an object is formed on the retina of a human eye. As the object moves closer to the eye, for a clear image to still be formed on the retina, what change occurs in the eye? the lens moves farther away from the retina the lens moves closer to the retina the lens' focal length increases the lens' focal length decreases (c) A clear image of an object is formed on the retina of a human eye. As the object moves farther away from the eye, for a clear image to still be formed on the retina, what change occurs in the eye? the lens moves farther away from the retina the lens moves closer to the retina the lens' focal length increases the lens' focal length decreases (d) A clear image of an object is formed on the film of a camera. As the object moves farther away from the camera, for a clear image to still be formed on the film, what change occurs in the camera? the lens moves farther away from the film the lens moves closer to the film the lens' focal length increases the lens' focal length decreases

Explanation / Answer

As the object moves closer to the eye, the focal length of the lens decreases to focus the image at the retina. Otherwise, the image would be formed beyond the retina.
