Answer:
Green, blue, indigo and violet.
Explanation:
The velocity of a wave is given by
[tex]v=f\lambda[/tex]
where
f = Frequency = [tex]5.45\times 10^{14}\ Hz[/tex]
[tex]\lambda[/tex] = Wavelength
[tex]\lambda=\frac{v}{f}\\\Rightarrow \lambda=\frac{3\times 10^8}{5.45\times 10^{14}}\\\Rightarrow \lambda=5.50459\times 10^{-7}\ m=550.459\times 10^{-9}\ m\\ =550.459\ nm[/tex]
The wavelength of the wave is 550.459 nm
Green light has wavelength which ranges from 500-565 nm.
So, the light which observed is green light and lower in wavelength than green light i.e., green, blue, indigo and violet.
