The Planck constant is a physical constant: the quantum of action in quantum mechanics, with an angular momentum. The Planck constant is the proportionality constant between the energy of a unit of electromagnetic radiation.
You may also be looking for the answer of "the speed of light."
Frequency = cycles/secondWavelength = distance/cycleFrequency * Wavelength = cycles/second * distance/cycle = distance/second = speed of propagation of that type of waveFor electrometric radiation in a vacuum this will be a constant across the entire spectrum, but not when the radiation is in a material medium. For other types of waves this may be constant or vary in complex ways across the spectrum.

It would probably be em waves
The Sun emits radiation across almost the entire electromagnetic spectrum.

The tendency for men and women to be employed in different occupations from each other across the entire spectrum of occupations.
If the first derivative if a function is a constant that the original function has only one slope across its entire domain, so it is a line.
the color spectrum
Black. it absorbs the entire visible spectrum, whereas white reflects the entire visible spectrum.
the color spectrum
I suppose you mean the visible spectrum, only a small part of the entire electromagnetic spectrum. The visible spectrum is basically all of the colors the human eye can detect.
