Question

Find the longest wavelengths of light that can cleave the bonds in elemental nitrogen, oxygen, and fluorine.

Answer 1

Longest wavelengths of light that can cleave the bonds in elemental nitrogen ,oxygen, fluorine is 1.27 x 10⁻⁷ m ,2.40 x 10⁻⁷ m,7.52 x 10⁻⁷ m

How do you calculate wavelength?

• Longest wavelengths of light that can cleave the bonds in elemental 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

• Longest wavelengths of light that can cleave the bonds in elemental 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

• Longest wavelengths of light that can cleave the bonds in elemental 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

Where ,

NA is Avogadro's number

h is Planck's constant

C is speed of light.

So, the longest wavelengths of light that can cleave the bonds in elemental nitrogen ,oxygen, fluorine is 1.27 x 10⁻⁷ m ,2.40 x 10⁻⁷ m,7.52 x 10⁻⁷ m.
