the wavelength of electromagnetic radiation is 400nm this wave number will be equal About the author Ayla
Answer: Wavenumber of a wave is defined as ν ~ = λ 1 , where λ is the wavelength. Given that wavelength of the photon is λ=400 nm=400×10 −9 m Thus, wave number is ν ~ =(400) −1 nm −1 =0.0025 nm −1 Reply
