Homework Help: chem

Posted by lyne on Friday, January 2, 2009 at 8:45pm.

a certain substance strongly absorbs infrared light having a wavelength of 3.75Ám. what is the frequency of this light in hertz?

i know that i have to use the equation c = frequency x wavelength and that c = 2.998 x 10^8 m/s. how do i convert that to Ám/s?

I think the answer will be 7.99 x 10^13, how do i find the units?
