What are the conditions necessary for an annular solar eclipse? A. Moon in perigee orbit; Moon moves a direct line between Sun and Earth; Moon in full moon phase.
B. Moon in perigee orbit; Moon moves a direct line between Sun and Earth; Moon in new moon phase.
C. Moon in apogee orbit; Moon moves a direct line between Sun and Earth; Moon in new moon phase.
D. Moon in perigee orbit; Earth a direct line between Sun and Moon; Moon in full moon phase.

B

Explanation:

An annular eclipse occurs when the Sun and Moon are exactly in line with the Earth, but the apparent size of the Moon is smaller than that of the Sun. Hence the Sun appears as a very bright ring, or annulus, surrounding the dark disk of the Moon.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
