Answer: The range of wavelengths of light that can be used to cause given phenomenon is
.
Explanation:
Given: 222 kJ/mol (1 kJ = 1000 J) = 222000 J
Formula used is as follows.

where,
E = energy
h = Planck's constant = 
c = speed of light = 
Substitute the values into above formula as follows.

Thus, we can conclude that the range of wavelengths of light that can be used to cause given phenomenon is
.
