Answer:
The energy of a photon depends on the frequency of the emission.
Explanation:
E = hν
where E is the energy of a photon, ν is the frequency of photon and h is Planck’s constant.
Energy of a photon is quantized and is directly proportional to the frequency of the emission.
Quantized energy of a photon explained the photoelectric effect. It was proven that light not has wave nature but particle nature as well. This later gave rise to wave particle duality of light waves.
Subtractive colors mixing with all three primaries will result in black.
<h3>How are the 3 primary subtractive colors combined?</h3>
Adding all three subtractive primary color filters together will absorb all the colors of the white light spectrum as appeared below. Each filter (or pigment) absorbs its harmonizing color and transmits (diffusely reflects) the others.
Primary colors union of these three results in white. The subtractive primary colors are related to the subtraction of light: cyan, magenta, and yellow, the colors used in four-color printing, the union of these results in black.
So we can conclude that the usually used subtractive primary colors are cyan, magenta, and yellow, and if you overlap all three in a successful equal mixture.
