The size of the smallest object that can be viewed as distinct depends on the resolving power of the optical system being used to view it. In general, the smallest object that can be resolved by the human eye without aid is around 0.1 millimeters. Beyond that, using tools like microscopes or telescopes can reveal smaller details.

Define magnification in lenss?
Magnification in lenses refers to the degree to which an object appears larger when viewed through a lens compared to when viewed with the naked eye. It is determined by the lens's focal length and the distance between the lens and the object being viewed. Magnification can be calculated by comparing the apparent size of the object through the lens to its actual size.
What is it called when an object that is viewed from different distances does not appear to become larger or smaller?
When an object viewed from different distances does not appear to change in size, it is known as size constancy. This perceptual phenomenon allows us to perceive objects as having a consistent size regardless of changes in viewing distance. Size constancy helps us accurately perceive the true size of objects in our environment.
When an object is is viewed through a convex lens held in front of a concave lens does the object get bigger or smaller?
When an object is viewed through a convex lens held in front of a concave lens, the object can appear either smaller or larger depending on the specific characteristics of the lenses and their relative positions. The combination of lenses can either magnify or reduce the size of the object.
What is the definition of power of magnification?
The power of magnification is a measure of how much larger an object appears when viewed through a magnifying device, such as a microscope or a telescope. It is calculated as the ratio of the apparent size of an object when viewed through the lens to its actual size. A higher magnification power indicates a greater level of enlargement.
What is the smallest object that can be seen under an electron microscope?

What is the smallest object visible to the human eye?
The smallest object visible to the human eye is about 0.1 millimeters in size, which is roughly the width of a human hair.

Definition of spatial resolution?
Spatial resolution refers to the size of the smallest object that can be resolved on the ground. In a digital image, the resolution is limited by the pixel size, i.e. the smallest resolvable object cannot be smaller than the pixel size. The intrinsic resolution of an imaging system is determined primarily by the instantaneous field of view of the sensor, which is a measure of the ground area viewed by a single detector element in a given instant in time. This resolution can often be degraded by other factors which introduce blurring of the image. such as improper focusing, atmospheric scattering and target motion. The pixel size is determined by the sampling distance

How would you estimate the size of object viewed under high power objective lens 40 times if you were given the size of the field diameter when using low power objective lens 4 times?
You can estimate the size of the object by comparing the field diameters observed under the low power objective lens (4x) and high power objective lens (40x). Calculate the ratio of the field diameters (40x/4x = 10), and use this ratio to estimate the size of the object viewed under the high power objective lens. Simply multiply the size of the object viewed under the low power objective lens by the ratio (field diameter at 4x) to get an estimation.
