Why does wave length determine minimum size an object can be seen?

There are some highly mathematical treatments of this question and it is usually handled as diffraction theory, but it is an interesting question to answer conceptually: The cutoff is not sharp, but generally small wavelengths need to be used to see small objects because small details have a lot of information, and long wavelengths carry very little information per unit of time. Here's an example to show why. Imagine you are blind (or just close your eyes) and try to determine what an object is by touching it with a large beachball. Let's imagine that the object is a wristwatch. No matter how many times you touch the wristwatch with the beachball, you probably won't be able to figure out what it is. If you used a smaller ball it would be much easier. If you used a ping pong ball you could pretty well determine what the object was. The same is true for microscopy; to see REALLY small stuff you need electrons to do the looking.

resolution
what causes shadow length?
The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.
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
When is an object can be seen?
when there's light .. :))
When can an object can be seen?
when it blocks incoming light,

Length, Width, Height, Volume, Mass, Weight
What is a minimum length for beam suppot on bearing wall?
That depends on what the beam is supporting above. Ideally 150mm bearing is the minimum. I have seen as little as 50mm! But any engineer would frown upon this.

What is the ratio of the size of the image seen with the microscope to the actual size of the object?
There is no constant ratio for image size to object size It depends on, 1. Image size 2. Sensor specifications (ex: Focal length of the camera) 3. Camera to Object distance 4. Acquisition angle (Theta) 5. Light focusing 6. Need some Known object values for determine unknown object size etc...
What was the first object to be seen under the microscope?
The first object to be seen under the microscope was poo.

How many hours in a day on the asteroid belt?
The "day" on any object in the solar system is very nearly the length of time the object takes to rotate on its axis ... or the length of time between as seen from its surface. The "asteroid belt" is a loosely contiguous group of millions of individual objects, and each one has its own "day".
