Answer: 557nm
Explanation:
Visible light has been known to have its wavelengths in the range between 400 to 700 nanometres (nm), or 4*10^-7 to 7*10^-7 m. This wavelength is between infrared and ultraviolet. Infrared has longer wavelengths and while on the other hand ultraviolet has shorter wavelengths. The wavelength of visible light has a frequency of approximately 430 to 750 terahertz (THz).
tanΦ= 0.0039/4 = 9.75*10^-4
Φ= tan^-1 (9.75*10^-4)
Φ= 0.056
λ= (5.7*10^-4) * sin 0.056
λ= 5.57*10^-7m
λ= 557nm
