During the flame test, an atom emitting a green color with a wavelength of roughly 550 nm would have a frequency of 5.45 1014 Hertz.
It may be explained in terms of the separation between any two identical succeeding locations on a wave, such as how the wavelength can be determined by calculating the separation between any two successive crests.
Speed of light = frequency of the green light ×wavelength of the light
3×10⁸ = 550×10⁻⁹ × frequency
frequency = 3×10⁸ / 550×10⁻⁹
= 5.45 ×10¹⁴ Hertz
Thus, the correct answer is option D.
