B. Infrared.
Explanation:
Referring to the electromagnetic spectrum, ultraviolet rays can be measured with a frequency of 10‐⁸, infrared has a frequency of 10‐⁵, visible radiation has a frequency of 0.5 x 10‐⁶ meanwhile X-rays show a frequency of 10‐¹⁰.
Hence, the largest magnitude among the rest goes to infrared rays, which makes B the correct answer.
Only a few ions (in comparison to others that totally break apart)
It determine Gibbs free energy
