How does the size of a barrier or opening affect the amount of diffraction of a wave?

Huygen's Principle tells us that, at each point that a propagating wave reaches, a spherical wave emanates outwards from that point.
When we're looking at a plane wave propagating (without a collision), the spherical emanations from each point on the wave front cancel out in all but the forward propagation direction, which is why a plane wave continues to travel as a plane wave.
When a wave strikes a barrier with a tiny opening in it, on the other side of the opening you can expect to see waves propagating outward radially from the opening.
When the opening is wider, the spherical waves coming from the points towards the center of the opening nearly cancel out, but at the edges of the opening there isn't anything to cancel out with, so if you're not in line with the opening (as in, if you look at the nearest point in the opening, your line of sight is not perpendicular to the original wavefront), you will see the wavefront coming radially from the opening edge nearest you. The closer you are (angularly) to being in front of the opening, the more plane-like the wave will be.
It is because of this same diffraction that we see an interference pattern when there are two small openings in the barrier. In this case, the radial waves will constructively and destructively interfere at different points beyond the barrier.

The amount of diffraction and thus the resolution of the scope depends upon?
the amount of diffraction depends on the opening of the slit and the wavelength of the light being used... resolution of diffraction on the screen also depends on the slit opening and the wavelength, but it more specifically depends on the angle at which the lit is shone, more on resolution, check out criterion for resolution........physics textbook do alot of clear explanation on that, check out physics for scientists and engineers, serway
What is the amount of diffraction?
there are several, depends!

wavelength and diameter of aperture.
How does diffraction affect the image produced by a telescope?
Diffraction occurs even in the best telescopes. The appearance of a star should be a dot with any amount of magnification, but under high magnification the star appears as a small disk with circular rings round it. The diameter of the disk does not indicate the size of the star but the size of the telescope's main lens, and a larger lens gives a smaller disk. Diffraction places a limit on the telescope's ability to separate the images of close double stars. The cloeset double stars can be viewed only with the largest telescopes.
Laws that limit the amount of trading carried on among nations is called?
A trade barrier is a law that limits the amount of trading conducted among countries. A tariff would be a well-known example of a trade barrier.
What is the difference between diffraction and dispersion?
Diffraction = The amount of light passing through a photographic lens being adjusted by a diaphragm. Dispersion = The splitting of light of different colors due to the different indices of refraction at different wavelengths when the light enters a lens or prism.
