Making Colors Flashcards
Why does a banana (e.g.) look yellow?
A banana looks yellow because it reflects the colour yellow into our eyes and absorbs all other colours.
Why do black objects look black?
Because they do not reflect any colours.
Why do white objects look white?
Because they reflect all the colours of light.
What are the three primary colours in physics?
Red, green and blue
(T or F) Filters only transmit certain colours of light. Explain your answer and give an example.
True, filters act similarly to coloured light. For example, if you shone red, green and blue light on a red filter only the red would pass through the filter and be reflected into our eyes, whereas the blue and green light would be absorbed.
What are the secondary colours in physics?
Magenta, yellow and cyan
(T or F) Some filters allow 2 colours of light to be transmitted. If True, give an example
True, for example if red, blue and green light were shone on a yellow filter, both red and green would be transmitted through the filter because yellow is made up of red and green.
