absorption spectrum

• What is the absorbtion spectrum?


  this is a graph that shows the amount of light absorbed by each photosynthetic pigment at each wavelength of light
• what absorbs a wider range of wavelengths primary or accessory pigments


  accessory pigments
• why is little light absorbed when the wavelength is between 530 and 640( the yellow and green region)


  this is because green light is reflected
• what colour is absorbed by all the pigments


  blue
• what colours are absorbed by chlorophyll a


  violet,blue and red
• what colours are absorbed by chlorophyll b


  blue and orange
• what colours are absorbed by carotenoids


  blue
• what is the range of wavelengths for chlorophyll a


  425nm and 675nm
• what is the range of wavelengths for chlorophyll b


  450nm and 640nm
• what is the range of wavelengths for carotenoids


  475nm
