Wavelength (l) and Frequency (n) Relationships c=ln ‚ where l is wavelength in meters n is frequency in hertz‚ 1/s or s-1 c=3.0 x 108m/s (the speed of light in a vacuum) Typical question #1- What is the frequency of red light with a wavelength of 690.nm? (1m=109nm) First- l is wavelength in meters‚ so convert nm to meters 690.nm ( 1m )=6.90 x 10-7m 109nm Now we can rearrange the equation above and solve for frequency‚ since
