<span>Answer:
We can use Rydberg's formula to find the wavelength if we know the energy levels.
The formula is: 1/w = R(1/L² - 1/U²) where w is the wavelength, L is the lower energy
level, U the upper energy level, and R is Rydberg's constant, experimentally found
to be 10,967,758 waves per meter for hydrogen.
If the atom is in the n=6 state, that means the lower energy level (L) is 6, and if we
ionize it, we remove the electron completely, so the value of U approaches infinity
so 1/U becomes zero. Now we can substitute known values into the formula and
we obtain: 1/w = 10967758(1/36 - 0) = (10967758)(0.02777777) = 304659.
So if 1/w = 304659 waves per meter, w = 3.282 * 10**-6 meter, or 3.282 microns.
That is the maximum wavelength of light that will ionize this atom, and it is in the
infrared region.</span>

Answer:
<em>The correct option is 2) I will subtract 18 days from the length of my shortest cycle.</em>
Explanation:
In order to use the calendar method of birth control, one might know hot to calculate the beginning and end of the fertile period.
The beginning of the fertile period can be calculated by subtracting 18 days from the length of the shortest cycle. This will determine the first unsafe day.
To calculate the end day, subtract 11 from the longest cycle of the person. This will determine the last unsafe day for the month.
The average length of a cycle cannot be used, but the individual's own shortest and longest cycles have to be used for calculation.
I think it would be 1 and 5
i hopes this help...if it don't can you let me know the answer also cause i would like to know
