Flashcards
visible light and colour
Cards in this deck (9)
- 1VISIBLE LIGHTmade up of a whole spectrum of different colours
Red - longest wavelength but lowest frequency
Violet - shortest wavelength but highest frequency - 2why is white and black not on the spectrumwhite - combination of all the colours
Black - an absence of light - 3objects appear a certain colour due to- wavelength of light hitting it
- properties of that object
(determine which wavelengths are absorbed, transmitted or reflected) - 4opaque objectsdont transmit any light
- 5transparent and translucent objectstransparent - transmits nearly all the light ( small fraction is absorbed or reflected)
Translucent - only transmit some of the light ( proportion of light transmitted determines how well we can see through)
ransmit light that hits them
(passes through) - 6the colour of the objects determines which colouris transmitted the mostgreen bottle
appears to be green because green is transmitted while the other colours are absorbed - 7colour filtertsused to filter out colours so that only certain wavelengths can pass through
(only transmit certain wavelengths of light while absorbing the rest) - 8primary colour filter - only allows primary colours to be filtered (red, green, blue)if you put white light through a green filter , only green light would be transmitted
if you look at a white object through a green filter it will appear as black because no light will be transmitted to the eyes - 9filters that arent for primary colourswavelengths of the primary colours can be added together to make that colour
inigo filer - will let through indigo but also blue and red because they make indigo
