Subtractive Color - Subtractive color explains the theory of mixing paints, dyes, inks, and natural colorants to create colors which absorb some wavelengths of light and reflect others. The color that an object appears t. Used . o have is based on what parts of the electromagnetic spectrum are reflected by it, or conversely by what parts of the spectrum are not absorbed.

Anything that is not additive col. Used . or is subtractive color. No other color mixing systems are known, except the imperfect system resulting from mixing real pigments, something that is very confusing nowadays.

Hertz - A unit of measure for frequency generally applied to waveforms, one Hertz is equal to one cycle in one second. It is abbreviated Hz so that 100 Hz would be 100 cycles per second. However, the unit m. Used . ay be applied to periodic events other than waveforms like the second hand on a clock, which would cycle at 1 Hz, or a human heart that may beat at 1.2 Hz. Named after the German physicist H. Used . einrich Rudolf Hertz, the name was established in 1930, but did not replace the term cycles per second until the 1970s.
