Photosynthesis The light that plants absorb to perform photosynthesis has a wavelength that peaks near 675 run. Express this distance in (a) millimeters and (b) inches.
Answer
Convert the units of wavelength from nanometer to meter and then convert it to millimeter and inch.
Wavelength of the light is given as follows:
(a) Convert the units of wavelength from m to mm.
Therefore, wavelength of light in mm is 
(b) Convert the units of wavelength from m to inches.
Therefore, wavelength of light in inches is
