Final answer:
When publishing a shadow cast image, the positive image is printed. Microscope images are typically virtual, inverted, and magnified. Negative magnification in lenses results in an inverted image, while lenses for nearsightedness create an upright and smaller virtual image.
Step-by-step explanation:
When you print a picture of a shadow cast image for publication, the positive image is usually printed. This is because a positive image is the direct representation of the original scene with proper tones and colors, as opposed to a negative image, which has reversed tones and is not typically used for display or publication without conversion into a positive.
The correct description of the image created by a microscope is that it is virtual, inverted, and magnified. This type of image is visible to the viewer through the microscope but cannot be caught on a screen, making it virtual. In addition, microscopes can have different configurations such as transmission electron microscope, scanning electron microscope, bright field microscope, darkfield microscope, and phase-contrast microscope, each providing a specific type of image enhancement or contrast for observing specimens.
For lens magnification, a negative magnification indicates that the image is inverted, whether it's real or virtual depends on the specific lens arrangement. A negative focal length lens, like those for nearsightedness correction, forms a virtual image that is upright and smaller than the object.
