∙ 7y agoTo 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.
It is 0.8 degrees.
It is approx 0.8 degrees.
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.
It is the two-dimensional image of the solid figure when it is viewed from points above the object. In mathematical terms (projective geometry), it is the projection of the figure onto a horizontal plane using the point at infinity as the centre of projection.

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.
Neptune appears as a small, bluish dot when viewed from Earth. Its angular size varies depending on its distance and position relative to Earth in its orbit around the sun. On average, Neptune's angular diameter is about 2.3 arcseconds when viewed from Earth.
Angular width refers to the extent of an object or region in terms of angle, typically measured in degrees or radians. It provides information about the size or scale of an object as viewed from a specific vantage point, taking into account the angular distance between its boundaries. In astronomy, angular width is often used to describe the apparent size of celestial objects, such as stars or galaxies, as observed from Earth.
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.
You can estimate the size of the object by comparing the field diameters observed under the low power objective lens (4x) and high power objective lens (40x). Calculate the ratio of the field diameters (40x/4x = 10), and use this ratio to estimate the size of the object viewed under the high power objective lens. Simply multiply the size of the object viewed under the low power objective lens by the ratio (field diameter at 4x) to get an estimation.
No, an ocular micrometer is used for measuring objects viewed through a microscope by comparing them to a scale etched onto the eyepiece. It is not designed to measure the diameter of a field of view.
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
