This was a problem on my Thanksgiving break chemistry homework. Some assistance would be greatly appreciated.

Why does electromagnetic radiation in the ulraviolet region represent a larger energy transition than does radiation in the infrared region?

Hint: 1) What is the range of wavelengths for ultraviolet radiation? What is the range of wavelengths for infrared radiation?

2) How do you calculate the energy of a photon?
