Solar Eclipse Amloh(b)

A solar eclipse occurs when the moon is between the sun and the earth and its shadow moves across the face of the earth. Eclipses are rare however most of the time , shadows do not overlap. Solar Eclipse, partial or total obscuring of the sun by the moon, with a resultant shadow cast upon the earth A partial solar eclipse can be seen when part of the earth is within the penumbra, or the outer portion of the moons shadow. The inner portion the umbra is formed by tangents to the sun and moon and the outer portion ,the penumbra is formed by tangents that intersect between the sun and the moon .these geometric regions occur because light travels in straight lines and casts shadows even at great distances.

During a total solar eclipse the moon completely blocks out the sun for long as seven to eight minutes .this type of eclipse is visible from the area on the earth with in the umbra the inner part of the moon shadow .the diameter of the umbra is never greater than 268.7 Km where it touches the surface of the earth.As a result the area in which a total solar eclipse is visible from the earth is never wider than that and it is usually.
