Answer 2

Image Formation in a Lens

When an object is placed in front of a lens, the image formed can vary based on the position of the object relative to the lens. There are three primary cases to consider: when the object is placed beyond the focal point, at the focal point, or between the lens and the focal point.

1. Object Beyond the Focal Point: - When the object is placed beyond the focal point of the lens, a real and inverted image is formed on the opposite side of the lens. - This type of image is referred to as a "real image." - The image is smaller than the object. - This occurs in convex lenses.

2. Object at the Focal Point: - When the object is placed at the focal point of the lens, no image is formed. - The light rays are refracted and do not converge to form a real image.

3. Object Between the Lens and the Focal Point: - When the object is placed between the lens and the focal point, a virtual and upright image is formed on the same side as the object. - This type of image is referred to as a "virtual image." - The image is larger than the object. - This occurs in convex lenses.

These principles are based on the behavior of light rays as they pass through the lens and are refracted. The specific characteristics of the image formed depend on the position of the object relative to the lens.
