It rather depends on the medium the light is traveling through.
In space, the speed of light is about 186282 miles per second.
So it would take
4350 / 186282 = 0.02335 s
or about 23 miliseconds
This is valid for all wavelengths
In materials, the speed of light is slower and is highly dependent on frequency
so the travel time would generally be longer.
Generally, the higher the frequency and the denser the material, the slower light goes passing through it. That's why a prism bends blue light at a greater angle than it does a red light in creating a rainbow.
For very low frequency light (long wavelength) a massive body such as earth may not even be relevant to the waveform, so the speed of light would remain as if in space alone. The mass of the earth would appear to slow (very slightly) the light passing by, but that is more due to the relative time dilation than to actually slowing light speed.
