Hello!
Whenever you see an atomic number with an element, you know the number of protons in the nucleus of the atom, which determines the chemical of an element and its place on the periodic table.
For example, Hydrogen has only one proton, however, if you were to add say 78 more protons, you'd get gold!
The correct answer should be D) The frequency of Wave 2 is double the frequency of Wave 1.
This is because the frequency is how many waves there is in an amount of time, so 10 waves in 1 second has double the frequency of 5 waves in 1 second.
Hope that helps!
