the minimium distance between the two meridians is at the poles because all the meridians comerge at the poles
The perpendicular distance is the shortest.
The center of Africa is between the Indian and Atlantic meridians.
because the north pole is 90 degrees latitude
The center of Africa is between the Indian and Atlantic meridians.
It is because all lines of longitude originate and converge there.
the minimum distance between two cable joint 2 meter (refer IEC 60052-4)
The lines running between the two poles are called meridians. These meridians are used in geographic coordinate systems to measure longitude and determine the angular distance east or west of the Prime Meridian (0 degrees longitude).
First of all, a meridian can be drawn at any longitude, there's no standard set of them, and there are actually an infinite number of possible different ones. So in order to get anywhere with this question, you'd have to specify which two of them you're interested in. But even if you named two meridians, there's no single answer to the question, because the distance between any pair of meridians changes. They're farthest apart where they cross the equator, and ALL meridians come together at a single point at the north and south poles. The distance in one degree of longitude is about 69 miles on the equator, and it shrinks smoothly to zero at the poles. The distance between any two meridians is (69 miles) x (degrees of longitude between them) x (cosine of the latitude where you measure it).
The wavelength (denoted by Greek letter Lambda) is the minimum distance between any two corresponding points on a wave that are in the same stage of the cycle. This distance is usually measured from peak to peak (crest to crest or trough to trough). Wavelength is a distance and is usually measured in meters.
Between the equator and either pole, no matter what interval you choose foryour display of the meridians of longitude, they all gradually converge, untilthey all meet in a single point at the pole. The space between any two meridians,at any latitude, is(the space between them at the equator) x (cosine of the latitude). But their behavior on both sides of the equator is perfectly symmetrical.That is, as you move farther from the equator, the meridians converge inthe southern hemisphere exactly as they do in the northern one.
