    a. (False): Micro-waves are less powerful than than ultraviolet radiations. Microwaves are higher wavelength radiations than ultraviolet. Wavelength is inversely proportional to the energy (power) of radiation. So, ultraviolet (low wavelength) radiations have higher energy (power) than that of microwaves (higher wavelength) energy. b. (True): Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants. Refer to the attached figure for absorption spectrum of Chlorophyll.
