SUMMARY
The discussion centers on calculating the wavelength of an electron with a kinetic energy of 2.00 eV. The incorrect application of the formula E=h(c/n) was identified as the source of error. Participants emphasized the necessity of using the correct value for Planck's constant, specifically 4.14 x 10-15 eVs, when working with energy in electronvolts (eV). This correction is crucial for obtaining accurate results in energy-wavelength calculations.
