What is the best description of the destructive interference of light? A mechanical wave meets an electromagnetic wave.

The crests of two waves intersect.

A longitudinal wave meets a transverse light wave.

The crest of one wave overlaps with the trough of another.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

The answer is probably c. xylem
