Question

convert the frequency from Hz to inverse centimeter cm-1. Enter a value without unit, using format 4.13E5

Answer 1

frequency = 4.13E^5 Hz

C = light velocity = 3 x 10^10 cm / sec

wave number = frequency / light velocity

                        = 4 .13 x 10^5 / 3 x 10^10

                       = 1.38 x 10^-5 cm-1

                       = 1.38 E^-5 cm-1

note : you did not give frequency value . i took your format given value for understanding 4.13E5. if you have original value just replace that value
