What else can I help you with?
What is the device that produces light of only one color?
A device that produces light of only one color is called a monochromatic light source. This can be achieved using devices like lasers, LEDs (Light Emitting Diodes), or filters to isolate a specific wavelength of light.
What is the color of the mixture of green and blue light called?
The color of the mixture of green and blue light is called cyan.
Why color of light is called color addition?
Because the combination of some colors produce the "white" light (color).
What is a light having one wavelength called?
At a single wavelength, it is called monochromatic
Why is it difficult to perceive color in dim light?
Your retina has more than one type of cell that perceives and transmits light. Cones are cells that respond to color, but they respond best in bright light. In very dim light, the cells that respond to light are called rods, which are blind to color.
What is a light red color called?
A light red color is commonly referred to as "pink."
Explain why mixing color of light is called color addition but mixing pigmean is called color subtraction?
Because it is.
What is it called when color appears to change with light?
This phenomena is called metamerism. It occurs when two colors appear to match under one light source but not under a different light source.
What is the difference between light and dark called?
color
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
What light color do you add to red light to get black light?
The color of light is made by adding all of the colors of parts of light, called wavelengths, together. Color is made by removing certain wavelengths of the light, and white is made by adding them all together. Black is the absence of light, so instead of adding a color of light to red, you will subtract the red light and leave no light.
What is the area beyond the color violet called?
The area beyond the color violet in the visible light spectrum is called ultraviolet light. Ultraviolet light has shorter wavelengths and higher frequencies than visible light, and is invisible to the human eye.
