Where can the object not be seen at the point of a converging lens?
According to the Physics Classroom, "When the object is located at the focal point, no image is formed."http://www.physicsclassroom.com/class/refrn/Lesson-5/Converging-Lenses-Object-Image-Relations
At the point of a converging lens the object cannot be seen.?
Yes, but it doesn't just float there in thin air. You need something there to make the image show up, such as smoke, tissue paper, fog, steam, ground (frosted) glass, etc. If you don't have any of those, you can take a short-focus eyepiece and look at the focal point with it. In the eyepiece, you'll see the image at the focal point. (It won't look like an image. It'll look like the object.)
Compared to its actual size how will an object seen through a convex lens appear?
LARGER!!
When an object is seen moving in relation to a stationary object is called the frame of reference or reference point?
When an object is seen moving in relation to a stationary object is called the frame of reference
Where should an object be placed in front of a convex lens to get a real image of the size of the objects?
The image seen through a convex lens will appear upright and enlarged when the object being viewed is within the focal length of the lens.

In a microscope you can see less of the obeject on this lens?
An object is seen less in the lens as a whole because it magnifies a specific part of the object.

What is the difference between point and shoot camera and DSLR camera?
A single lens reflex (SLR) is a camera that uses the same set of lenses to both focus the image on the CCD (digital) and enable the photographer to frame the picture. That is to say, when you look through the viewfinder of a DSLR you are looking directly at the object through the main lens. You are not looking at the digitally re-created picture of the object or through some other lens that is off-center of the main lens. A point-and-shoot camera will have some other mechanism for framing the picture.

It can be.
Why must a small object seen through an ocular lens be centered in the field of view before changing to a higher power objective lens?
prevent its disappearance due to the decrease in the field of viewTo do just that... center the object, because when the magnification is increased, the lens zooms in on the center, cutting out the perifery.
What is the closest point at which clear focus is possible?
''Near Point -- the closest ''point from the eye at which an object can be clearly seen.''''
