Extraneous light refers to unwanted light that enters a system and interferes with the desired output or effect. This light can come from various sources such as ambient light, reflections, or stray light within the system, leading to reduced contrast, image quality, or accuracy in measurements. Managing extraneous light is critical in fields like Photography, optical instruments, and scientific experiments to ensure reliable results.
A traffic light is a light source as it emits light to signal drivers when to stop, slow down, or go.
A red light will be needed to combine with magenta light to produce green light. Green light is the complementary color to magenta, so by mixing red light with magenta light, the result will be green light.
Mixing red light and blue light produces magenta light.
White light is a combination of all colors of light. To obtain white light, blue light can be combined with red and green light in specific proportions. Red light and green light mixed with blue light create an additive color mixture that results in white light.
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
extraneous " not pertinent; irrelevant: an extraneous remark; extraneous decoration."
During the long, boring lecture, most people agreed that much of the information was extraneous.
Extraneous means 'coming from the outside'.
The crowd's not entirely silent, but there's not too much extraneous talking.
One handy way to dodge a difficult question is to earnestly begin talking about something extraneous to it.
No. Sometimes they are both extraneous.
The lab technicians said that the stray hair found on the toilet seat was from a previous guest who'd stayed in the hotel room, and was totally extraneous to the investigation.Exactly what I saw that night, I'm not sure, but it was extraneous to this plane of existence, and it still gives me nightmares.All seem to make values depend on extraneous factors.Many people may not want all this extraneous software cluttering up their hard drive.
No. Essential means that the thing is very important; an "essence." Meanwhile, extraneous means that the thing is something "extra," and not needed.
Extraneous means extra and unnecessary. Extraneous solutions are values that can arise from the process of solving the equation but do not in fact satisfy the initial equation. These solutions occur most often when not all parts of the process of solving are not completely reversible - for example, if both sides of the equation are squared at some point.
