Why in telescopes and microscopes the ocular distance is such that it creates virtual images instead of real images?

Telescopes and microscopes use virtual images because they allow for magnification and manipulation of the image without physically moving the object being viewed. This is especially important for astronomical and microscopic observations where the object is too far away or too small to be seen with the naked eye.
Virtual images in telescopes and microscopes are created through the use of lenses or mirrors. These optical components bend and focus light rays to create an enlarged and magnified image of the object being viewed. The image appears to be in a different location than the actual object, hence the term "virtual".
No, virtual images can only be seen through the use of optical instruments such as telescopes and microscopes. This is because the lenses and mirrors in these instruments are specifically designed and positioned to create a virtual image at the eyepiece or viewing point.
Not necessarily. The orientation of the virtual image depends on the type of lens or mirror used in the instrument. For example, a convex lens will create an upright virtual image, while a concave lens will create an inverted virtual image. Mirrors can also produce different orientations of virtual images depending on their curvature.
There are several advantages to using virtual images in telescopes and microscopes. First, they allow for magnification of small or distant objects, making them easier to study. They also allow for manipulation of the image through the use of different lenses or mirrors. Additionally, virtual images are not affected by the physical properties of the object being viewed, such as color or texture, allowing for a clearer and more focused image.
