Light passing through a double slit with separation d=2.42*10^-5 m creates its second maximum (m=2) at an angle of 2.74 deg. What is the wavelength of the light, in nanometers?
(Hint: The answer will be between 400 and 700.) (Unit=nm)

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.
