True or false: a. microwaves are more powerful than ultra-v1olet waves. b. chlorophyll in green vegetation absorbs mainly in the visible region of the emr spect

a.Microwaves are not more powerfull as it's frequency is lower so energy will be also low. as E=hf we know so False b.yes it's true chlorophyll absorbs green and red visible ...

a. (False): Micro-waves are less powerful than than ultraviolet radiations. Microwaves are higher wavelength radiations than ultraviolet. Wavelength is inversely proportional to th...
