Lenses are used in a variety of everyday applications. In a camera, light from a source passes through a lens and an opening, called the aperture, and forms a real image that is recorded by film or a sensor. The size and shape of the aperture affects how much light strikes the film or sensor; they also have an effect on some characteristics of the image. In this experiment, you will investigate the role of the aperture in image formation.
In this experiment, you will
- Predict and observe the effect of the size and shape of the aperture on the formation of a real image.
- Observe how the size of the aperture affects the depth of field.
- Observe how focal length and object distance affect the depth of field.
