Answer:
ν ≈ 4.7 × 10¹⁴ Hz
General Formulas and Concepts:
<u>Chem</u>
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
λ = 6.4 × 10⁻⁷ m
<u>Step 2: Solve for ν
</u>
3.0 × 10⁸ = 6.4 × 10⁻⁷ · ν
ν = 4.6875 × 10¹⁴ Hz
<u>Step 3: Check</u>
<em>We are given 2 sig figs. Follow sig fig rules.</em>
4.6875 × 10¹⁴ Hz ≈ 4.7 × 10¹⁴ Hz

Nutrients are synthetic substances found in each living thing on Earth. They are important to the existences of individuals, plants, animals, and any remaining organisms. Nutrients assist break with bringing down food to give organisms energy. ... The main nutrients they need are carbon, hydrogen, and oxygen.
Natural formation of lead occurs by radioactive decay of uranium and thorium through radon (222Rn). Four stable isotopes are known, 204Pb, 206Pb, 207Pb and 208Pb, the first three of which are used for estimating the ages of rocks. Lead compounds exist mainly in +2 or +4 oxidation states, the former being more common.
Protons cannot be so easily added to an atom, so this method cannot be used to produce ions. Protons are found in the nucleus which is held together by strong forces. This means that its structure is not easily changed. Bombarding it with a proton may even cause its decay, just as in nuclear fission a nucleus is bombarded with neutrons.
