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.

How can I measure the size of an object from an image?
One way to measure the size of an object from an image is to use a known reference object of a standard size in the same image. By comparing the size of the reference object to the size of the object you want to measure, you can calculate the size of the object in the image.

How do i find magnification of the image?
To find the magnification of an image, use the formula ( \text{Magnification} (M) = \frac{\text{Image Height}}{\text{Object Height}} ) or ( M = \frac{\text{Image Distance}}{\text{Object Distance}} ). If you have the dimensions of the object and the image, divide the height of the image by the height of the object. Alternatively, if you have the distances from the lens to the image and the object, use the second formula for magnification.
How many times larger an image is then the original object?
The size of an image compared to the original object is determined by the magnification factor, which is the ratio of the image size to the object size. For example, if an image is 10 centimeters tall and the original object is 2 centimeters tall, the image is five times larger than the original object. This relationship can be expressed as the formula: magnification = image size / object size.

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?
You do not see the top of the object and the bottom of the object being turned over. When you stand in front of it, your head remains at the top and your legs remain below. All it does it invert the object laterally. When you raise your right hand, the image raises the left hand.
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.
Differentiate real image from virtual image?
Real images can be obtained on the screen,whereas virtual images can't be obtained on the screen
