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.

Wave length determines the minimum size an object can be seen because smaller objects will scatter light waves in different directions. Shorter wavelengths are less prone to this scattering, allowing us to see smaller objects more clearly. This phenomenon is known as diffraction, and it sets a limit to the resolution of optical systems.

The minimum distance between two object before they are seen as one object is known as?
The minimum distance between two objects before they are seen as one object is known as the resolution limit or the resolving power of the imaging system. It is the ability to distinguish between two separate objects rather than seeing them as a single entity.
what causes shadow length?
The length of a shadow is primarily determined by the angle of the sun in relation to the object casting the shadow. Shadows are longer in the early morning and late afternoon when the sun is lower in the sky, and shorter at midday when the sun is directly overhead. The size and shape of the object casting the shadow also play a role in determining shadow length.
What determines the characteristics of images seen through a magnifying glass?
The characteristics of images seen through a magnifying glass are determined by the magnification power of the lens, the distance between the lens and the object being viewed, and the focal length of the lens. These factors affect the size, clarity, and distortion of the image.
What does a microscope do to an object?
A microscope magnifies an object, allowing small details to be seen more clearly. It uses lenses to focus light on the object, enabling observers to view it at a level of detail not possible with the naked eye.
When is an object can be seen?
An object can be seen when light reflects off of its surface and reaches our eyes. This happens when there is sufficient light in the environment for our eyes to detect the object.
What are the qualities of an object that can be seen and measured without changing the object?
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?
The ratio of the size of the image seen with the microscope to the actual size of the object is known as the magnification of the microscope. This ratio indicates how much larger the image appears compared to the actual size of the object being viewed.

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".
When is an object can be seen?
An object can be seen when light reflects off of its surface and reaches our eyes. This happens when there is sufficient light in the environment for our eyes to detect the object.
Meaning of tensional force?
Tensional force is a pulling force that occurs when an object is being stretched or pulled in opposite directions. It is commonly seen in objects like ropes, cables, and springs, where the force is applied in a way that creates tension along the length of the object.
What is the direct object in the sentence Have you ever seen that play?
The direct object is "play".
