Web1 dec. 2014 · All electromagnetic waves will travel at around the same speed in a vacuum. The differences are negligible so we just refer to the speed as c, or the speed of light which is 3.00 × 10 8 m / s. The 700 n m and 400 n m you are referring to is probably referring to wavelength which is usually measured in n m because it is so small.
