For uv light of wavelength 254 nm calculate the frequency, Ask an Expert

Academics

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
