# Does speed of light depend on the wavelength or frequency of it?

nineteen
I heard that the speed of light doesn't depend on the wavelength or frequency of it, how does it happen? I don't understand it because the ultimate equation is c = fλ (where c is the speed of velocity of light, f is the frequency and λ is the wavelength of it...).

As the frequency increases the wavelength decreases, so their product doesn’t change.
