Find the longest wavelengths of light that can cleave the bonds in elemental nitrogen, oxygen, and fluorine. the average bond energy of n-n bond is 945 kj/mol, oxygen is 498 kj/mol, and f-f is 159 kj/mol. give your answers in scientific notation.

For Nitrogen:

wavelength = NA x h C / bond energy

= 6.022 x 10²³ x 6.626 x 10⁻³⁴ x 3 x 10⁸ / (945 x 10³)

= 1.27 x 10⁻⁷ m

For Oxygen::

wavelength = NA x h C / bond energy

= 6.022 x 10²³ x 6.626 x 10⁻³⁴ x 3 x 10⁸ / (498 x 10³)

= 2.40 x 10⁻⁷ m

For Fluorine:

wavelength = NA x h C / bond energy

= 6.022 x 10²³ x 6.626 x 10⁻³⁴ x 3 x 10⁸ / (159 x 10³)

= 7.52 x 10⁻⁷ m

(NA is Avogadro's number, h is Planck's constant and C is speed of light)
