It is approx 0.8 degrees.
It is 0.8 degrees.
To find the angular size, we need to convert the distance to the object into radians. 4 yards is approximately 12 feet or 144 inches. The angular size can be calculated as the diameter of the object (1 inch) divided by the distance to the object (144 inches), which equals approximately 0.0069 radians.
No If you have a picture of it you can use the measurements you know to give you the scale of the picture. Or if you don't have a picture you can use the length of your thumb viewed at arms length, and then calibrate using a known object, or better still, the known width.
The number of visible sides if one if viewed from the front or side. The elevation from an angular position would give two face whereas all four triangular faces will be visible from above. So the answer will depend on the viewing position. In every case, the dimensions of the triangles would be required to find the visible surface area.

Since it is a small angle, just divide the diameter by the distance. Be sure to convert everything into the same units first. The answer will be in radians.
Convert everything to the same units (I suggest inches), then divide the 1 inch by the equivalent of the 2 yards. That will give you the approximate angular size, in radians.This works because 1 inch is much smaller than 2 yards.
In michelson interferometer the mirros are perpendicular and because of our eye viewed direction and angle theta the fringes are circular
No Way..!
the lens or system of lenses in a telescope or microscope that is nearest the object being viewed
the naswe is 400

To determine the total magnification of an object being viewed under a microscope, multiply the magnification of the ocular lens by that of the objective lens.
