How does light wavelength affect photosynthesis? The best wavelengths of light for photosynthesis are those that are blue (375-460 nm) and red (550-700 nm). These wavelengths are absorbed as they have the right amount of energy to excite electrons in the plant's pigments, the first step in...
3 (a) A coherent source of light of wavelength 650 nm is incident normally on a double slit with separation 0.250 mm as shown in Fig. 3.1 below. An interference pattern of bright and dark fringes is observed on the screen placed2.00 m away from the slits.screen(not to scale)double slit...
