Atomic Structure & Periodicity

Atomic Structure & Periodicity. Electromagnetic Radiation. wavelength and frequency are inversely related. n = c/ l Photosynthesis uses light with a frequency of 4.54 x 10 14 s -1 . What is the wavelength of this light? 4.54 x 10 14 s -1 = 3.0 x 10 8 ms -1 / l l = 6.60 x 10 -7 m.
