Homework Answers
a)
Given,
The dissociation energy of a carbon-bromine, E = 210 KJ/mol
The energy per bond, E = Total energy / Avogadro's number
= 210 * 1000 / 6.022 * 1023
= 3.487 * 10-19 J
E = hc / 
The wavelegth,
= hc / E
= (6.626 * 10-34 * 3 * 108) / 3.487 * 10-19
= 5.70 * 10-7 m
= 570 nm
b)
The wavelength 570 nm represents the visible region.

calculations involving wavelength, frequency, and energy.
Several properties are used to define waves. Every wave has a
wavelength, which is the distance from peak to peak or
trough to trough. Wavelength, typically given the symbol λ
(lowercase Greek "lambda"), is usually measured in meters. Every
wave also has a frequency, which is the number of
wavelengths that pass a certain point during a given period of
time. Frequency, given the symbol...
