Question

The total energy of a mole of photons of a particular type of IR light is 10.7025 kJ.

What is the wavelength of this radiation? Use 3 sig figs in your answer.

Expert Solution
Step 1

Energy of one photon is inversely proportional to the wavelength of the radiation. Higher the energy of a photon, lesser will be the wavelength associated with it.

                                                                       E=hcλ             (equation 1)

Here, h is the Planck's constant (6.626×10-34 J·s), c is the speed of light (3×108 m/s) and λ is the wavelength.
