Disagree.
Fluoresce objects will only glow when put under actual Ultraviolet light. This is due to the molecules becoming excited by the ultraviolet radiation.
Microwaves give micro-waves that are present in another spectrum of wave length and will not be able to fluoresce the molecules. If it’s not “ultra violet “.... it’s not going to glow.
Energy is measured in units called joules.
answer: a. joules.
The amplitude will be the distance from the mid point of the variations to the crest. That would be 1.2/2m = 0.6m
