Molecules = A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

a. Mg S  = Magnesium and sulfur both are atoms, we both can find them on the periodic table

b. H2 SO3  =  H2 is a molecule that contains 2 hydrogen atoms

SO3 is a molecule that contains 1 sulfur atoms and 3 oxygen atoms

Green light has a frequency of 6.01 x 10^14 Hz. What is the wavelength? (Round to the nearest hundredth) *​
Ivahew [28]

Answer:

4.99 x 10⁻⁷ meters or 499 nanometers

Explanation:

Use the formula:

λ = c/ν, where λ = wavelength, c = the speed of light (it's constant, 2.998 x 10⁸ m/s), and ν = frequency

λ = (2.998 x 10⁸ m/s)/(6.01 x 10¹⁴ 1/s)

λ = 4.98835 x 10⁻⁷

Round to nearest hundreth and you get 4.99 x 10⁻⁷ meters, or 499 nanometers.
