Recognizing patterns of cause and effect is an important analytical skill that allows historians to explain why things happened the way they did in the past. It's also a strategy that can make it possible to predict what may happen in the future.

Atom: the basic unit of an element

Atomic theory of atoms: a theory that states that all matter is made of atoms that cannot be divided or destroyed

Element: a substance that cannot be broken down into a simpler substance

Gas: the state of matter that does not have a definite shape or a definite volume

Liquid: the state of matter that has an indefinite shape but a definite volume

Magnetic field: a region around a magnetic material or moving electric charge

Particle: a tiny piece of matter

Phase: a unique form of the existence of matter

Plasma: an ionized gas of positively and negatively charged particles

Scientific theory: an explanation for some naturally occurring event, developed from extensive observations, experimentation, and reasoning

Solid: the state of matter that has a definite shape and volume

Therefore, I hope this helps And Good Luck!

How to calculate the frequency of an ion
sergij07 [2.7K]

solution:

You need to find the frequency, and they have already given you the wavelength. And since you already know the speed of light, you can use formula (2) to answer this problem. Remember to convert the nano meters to meters because the speed of light is in meters. (1 nm = 1.0 x 10^{-9} m)

v=c\lambda \\v= (3.00 \times 10^8 m/s)/(6.9\times 10^-7 m) \\v = 4.35 \times 10^{14} s^{-1}
