Ответ:
A
Explanation:
1 nm is equal to 1x 10^-9 meters, therefore 225 nm is just 2.25 x 10^-7 meters. E is the smallest and therefore the most powerful, so it's not the answer.
The longer the meter, the weaker it is, meaning A is the longest of all of them making it the lowest energy wavelength of the list.
I hope this helps and good luck with your physics assessment!
