When you look at a lamp through a green filter, the lamp will appear green if it emits green light or reflects green wavelengths. If the lamp emits other colors, such as red or blue, those colors will be filtered out, making the lamp appear dark or black, as the green filter only allows green wavelengths to pass through. Thus, the perceived color depends on the light source's color and the filter's properties.
A cyan colored surface will reflect any blue or green light that is incident. The green filter will remove all colors of light passing through it except green. The book is illuminated with only blue light. Draw your conclusion.
BLUE
Yellow-green.
due to presence of green colour photosynthetic pigment known as Chlorophyll
A blue object would appear darker when viewed through a green filter because the green filter would absorb some of the blue light that the object reflects, resulting in a more subdued color.
Green objects would appear green and red objects would appear very dark.
BLACK
if a red cricket ball was viewd in red light it would appear to be the colour of black or blue that's what colour you would be if it hit youin the face lol.
green
To make green appear black, shine red light on it. Green absorbs red light, so when red light is shone on green, the green will appear black.
you use a green filter in front of the light and you should just get green light passing through as all the other colours are absorbed by the filter. the filter would just be a sort of plastic thing which is green in colour :)
