This phenomenon is known as additive and subtractive color mixing. When red, green, and blue light overlap, they combine to create white light, demonstrating additive mixing. However, when a slit is used to block parts of this white light, subtractive color mixing occurs as specific wavelengths are filtered out. The slit acts as a filter, allowing only certain colors of light to pass through. This selective filtering leads to shadows formed by the absorption of specific wavelengths, resulting in

The phenomenon observed here involves both additive and subtractive color mixing. When red, green, and blue lights combine, they form white light through additive mixing. However, when a slit blocks portions of this white light, subtractive color mixing occurs. The slit acts as a filter, allowing specific wavelengths of light to pass through. As a result, shadows cast by objects appear in cyan, magenta, and yellow. These shadows arise because each primary color in the additive model corresponds

Follow @physics_unplugged | video description 👇 The phenomenon we are seeing is called additive and subtractive color mixing. When blue, green, and red light combine, they create white light due to additive mixing. However, when you use a slit to block parts of this combined white light, you’re engaging in subtractive color mixing. The slit essentially acts as a filter, allowing only certain wavelengths of light to pass through. Shadows cast by objects result from the selective absorption of ce

RGB Additive Color Mixing Demo: three LEDs projected onto a translucent screen demonstrate the additive nature of our perception of colored light. Three potentiometers allows the user to adjust the intensity of each color. Mixing Red, Green, and Blue to create Yellow, Magenta, and Cyan with the following mixings: R G=Y, G B=C, and R B=M. Adding all three R G B produces White. RGB color addition is the basis for all computer and TV displays- all the colors you are looking at right now on your scr
