Object distance refers to the distance between the object being observed and the lens of a microscope or telescope. It is measured in millimeters (mm) or centimeters (cm) depending on the scale used.
The closer the object is to the lens, the larger it will appear, resulting in a higher magnification. Conversely, a further object distance will result in a smaller image and lower magnification.
Magnification is the process of making an object appear larger than its actual size. It is achieved by using lenses or other optical devices.
Magnification is calculated by dividing the size of the image by the size of the object. For example, if the size of the image is 10mm and the size of the object is 2mm, the magnification would be 5x (10mm/2mm = 5).
Yes, there is a relationship between object distance and field of view. As the object distance increases, the field of view also increases, resulting in a wider view of the object. This is why adjusting the focus of a microscope or telescope can change the field of view.
