I looked it up. The amplitude of a wave is a measure of the displacement of the wave from its resting position.
I’d have to say C. battery.
Answer:
energy of photon=1.824ev
Explanation:
given wavelength of ligt=6.8×10⁻⁷m=6800A⁰
energy of photon(E)=hc/λ;
and for simplicity
E=12400/λ
where λ is aken in angstorm
and energy in ev
E=12400/6800ev
E=1.824ev=energy of photon
Although there is alot of water on earth some of it is contaminated and could be harmful for us to drink .Therefore people don't drink it in order to not get sick.
