(answer 10.2 eV, 121.6 nm) 7. 1 eV = elementary charge * 1 V=1.602 x 10- 19 J. For Financial dates and legal dates, days between dates, days before a date or days after a date, day of the week for a given date in history, involving the last 2 centuries approximately, we suggest that you use our Julian to current day and date calculator. *Constants taken from a chapter written by B. E. Deal in Semiconductor materials and process technology handbook : for very large scale integration (VLSI) and ultra large scale integration (ULSI) / edited by Gary E. McGuire. Higher, or wider bandgap materials will convert shorter wavelength, higher energy light. A photon with a wavelength of 532 nm (green light) would have an energy of approximately 2.33 eV.Similarly, 1 eV would correspond to an infrared photon of wavelength 1240 nm or frequency 241.8 THz. 6.
