What is the wavelength of light with a frequency of 7.26 x 1014 Hz? What region of the EM spectrum would this lie in? c xxV = & 3 00x108 x x(7 26 x 1014 H2) Vex = . = . > 26x10i V e . = W L . Frequ =3 00x18 H2 , Mi 10 meter 413nm Violet b. What is the frequency of radiation with a wavelength of 442 nm. What region of the EM spectrum would this lie in? 21 1 , x 804108m/s" 6 79410/5+2 3 00x108= -m= 3 /2) . . . X2nm - 442x10 - 44 convert to i not nm Just put - = Z 3 XI0 4 zum 109 c. What is the energy of a photon with a frequency of 7.26 x 1014 Hz. What region of the EM spectrum would this lie in? E = hp ~ 16 . 62x1024) /7 . 26x107 14Hz = 4 / . 1x18 S d. What is the wavelength of a photon of energy 2.4 x 10-16J? What region of the EM spectrum would this lie in? E c = n hir -V = xV = C I = 2. The energy to break 1 mol of C-C bonds (that is 6.022 x 1023 C-C bonds) is 348 kJ/mol. What would be the minimum frequency of a photon that would break a single C-C bond?
