What is shape index?
Shape index is a feature used in image processing to describe the shape of objects within an image. It quantifies the roundness or elongation of an object by comparing its area with the area of a circle with the same perimeter. This provides a numerical measure to differentiate between different shapes in an image.
How does the image distance compare to the object distance?
The image distance is the distance from the lens to where the image is formed, while the object distance is the distance from the lens to the object. In general, for real images, the image distance is different from the object distance. For virtual images, the image distance is negative and the object distance is positive.
Why if you move the object away from the lens the size of the image get smaller?
Moving the object away from the lens increases the object-image distance. According to the thin lens equation, as the object-image distance increases, the image distance increases incrementally more than the object distance. This results in a smaller image size due to the inverse relationship between image size and image distance.
What is the difference between the object and the image?
An object refers to the physical thing being observed, while an image is a reproduction or representation of the object, typically in a visual form. The object exists in reality, while the image can be a reflection, photograph, drawing, or any other representation of the object.
A change in the size of an image compared with the size of an object?
The change in size of an image compared with the size of an object is termed magnification. This can be calculated as the ratio of the size of the image to the size of the object. Magnification can be expressed as magnification = image size / object size.

Why mirror image is called upright image?
A mirror image is called an upright image when the image appears in the same orientation as the object being reflected. This means that the top of the object is at the top of the image and the bottom of the object is at the bottom of the image, creating a true-to-life reflection.
Differentiate real image from virtual image?
Real images can be obtained on the screen,whereas virtual images can't be obtained on the screen
What is a difference between the mirror image and the object?
A mirror image is a reflection that appears to be reversed left to right, while an object is a physical entity that exists in space. In a mirror image, the image appears as if you were looking at the object's reflection in a mirror.
Images formed by a plane mirror?
The image formed by a plane mirror is a virtual, upright, and laterally inverted replica of the object. The distance between the object and its image in a plane mirror is twice the distance of the object from the mirror. The size of the image is equal to the size of the object.
What type of image is formed when object is kept at F for a convex lens?
For a convex lens the focal point is the transition point between getting a real image and a virtual image. If the object is at a greater distance then F you get a real image. If the object is closer to the lens then F you get a virtual image. If the object is located at F the light rays from the object leave the lens parallel and never form any kind of image.
