Question

URGENT PLEASE HELP!!

Answer 1

Answer:

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!
