v=hc/lambda....
v=6.626×10^-34×3×10^8/550×10^-9
=0.036×10^17
v=3.6×10^15Hz
v=6.626×10^-34×3×10^8/550×10^-9
=0.036×10^17
v=3.6×10^15Hz

Answer:
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.
