An extremely thin sheet of glass is being inspected at the camera store. illuminated by white light at near-normal incidence, the film-like sheet is 0.400 µm thick and has air on both sides. if the glass has a refractive index of 1.52, what wavelength of visible light (in nm) does it reflect most strongly? (the wavelengths of visible light range from 400 to 700 nm.)

Sorry i don’t know what to do

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
