### Question 1.55 6th edition

I was wondering why for the problem "In infrared spectroscopy, it is common to express energy in terms of frequency/c, with the units cm-1 (read
as reciprocal centimeters). (a) If an absorption occurs in the infrared spectrum at 3600 cm -1, what is the frequency of radiation that corresponds to that absorption? " the answer is 1.1E14 s-1 because i keep getting 1.1E10 s-1 by converting 3600 cm-1 to 36 and then multiplying by 3E8 m/s

I think your answer is right. We went over this question in my discussion and we got 1.08*10^10 1/s.
