speed of light= wavelength× frequency
1 nm=1×10*-9m
3×10*8/550×10*-9
so frequency=5.4×10*14 Hz
1 nm=1×10*-9m
3×10*8/550×10*-9
so frequency=5.4×10*14 Hz

let me take lamda as 'y' here and nu as 'v' here. c is speed of light in air or vacuum
original formula : c = wavelength of given light (lambda) × frequency of light (nu)
here we change it a bit making it like this..
v = c/y
i.e.
v = 3×10^8/5.50×10^-7
(1 nanometer equals 10^-9 meter)
after solving we get,
v = 5.4×10^14.
have a good day
