- Magnification, Cameras and Projections
- Convex lenses create magnified images
- The object being magnified must be close to the lens
- The image produced is a virtual image
- The image on the sensor on a camera is a real image
- Light from the object travels to the camera and is refracted by the lens
- The image is inverted and the object is further away then the focal lens
- Projectors make the image larger than the object
- When you project an image, the obkect is placed upside down and close to the lens
- The light from the object is refracted by the lens producing a real image
- Images are focused by moving the lens
- The closer the object is to the lens, the further from the lens the image will be
- Magnification = image size/object size
- Convex lenses create magnified images
