I need help with my Science HWplease help me.Just a little recap: Additive Theory of light is when you mix blue and red light to make magenta, green and red light to make yellow pigment, and green and blue light to make cyan pigment.
If its first wash then hand wash it two times by means of hand sure two times however now not an excessive amount of powder you'll then rinse it - now not fully simply adequate to get such a lot of cleaning soap out then positioned it in washing laptop for a well rinse and spin. Follow recommendations for tumble drying. You must, if the colors have now not run, wash it with whites in long run. If washed with coloureds it'll decide on up the darkish wash onto the white.
Black is the absence of colored light.
Ok, check the difference between light and pigment. While it is true that mixing green light and red light, you get yellow light.it is NOT true that mixing green light and red light gives you yellow pigment. Pigments aren't part of the question of additive theory of light. They are part of the subtractive theory of colored objects. Debating whether white or black are colors is really unnecessary. They still *are* colors, by the simplest definition of the word color. Color is the visual perceptual property. You can still visually perceive black, and you can still visually perceive white, therefore they still qualify as colors. What certainly is the case about the color black, is that there is no such thing as black light, except when used as a figure of speech name for UV lamps. Black is the absence of light. Black is the default image of no incident light. Contrast this with white. White is the balanced mixing of colored light. White light is COLORFUL. To make white light visible to humans, at a minimum, you need to mix two opposite colors of light, like red and cyan. White light can be accomplished in numerous ways, it can be a mix of a continuous spectrum of all colors of light, or it can mix selective colors that can stimulate all three of a human's cone cells (such as red/green/blue).
