For UV light of wavelength 254 nm, calculate the frequency and the amount of energy absorbed by a single molecule when it absorbs a quantum of this light. (Remember ??=c, where c = 3.00 x 108m/s and E = h?, where h = 6.63 x 10-34 J·s) 1nm = 1x10-9m.
a. ? = 8.5 x 10-7 s-1 and E = 5.6 x 10-40 J
b. ? = 8.4 x 10-16s-1 and E = 5.6 x 10-49 J
c. ? = 1.2 x 106s-1 and E = 8.0 x 10-28 J
d. ? = 1.2 x 1015s-1 and E = 7.8 x 10-19 J
