Bond Energy and Wavelength Calculations

The video tutorial explains how to calculate the maximum wavelength of light required to break a carbon-carbon triple bond by absorbing a single photon. It starts by discussing the energy needed to break a mole of such bonds and then converts this energy to break a single bond using Avogadro's number. The tutorial then applies the E=HC/λ formula to find the wavelength of light in meters and converts it to nanometers for convenience, resulting in a wavelength of 143 nanometers, which falls in the UV light range.
