Questions & Step-by-Step Solutions

Which wavelength of light is least effective for photosynthesis? (2022)
  • Step 1: Understand that photosynthesis is the process plants use to convert light into energy.
  • Step 2: Know that chlorophyll is the green pigment in plants that absorbs light for photosynthesis.
  • Step 3: Learn that chlorophyll absorbs light most effectively in the blue and red wavelengths.
  • Step 4: Recognize that green light is not absorbed well by chlorophyll.
  • Step 5: Conclude that since green light is mostly reflected and not absorbed, it is the least effective for photosynthesis.
