SUMMARY

Electromagnetic radiation in the ultraviolet (UV) region represents a larger energy transition than that in the infrared (IR) region due to the shorter wavelengths associated with UV radiation. The wavelength range for UV radiation is approximately 10 nm to 400 nm, while IR radiation ranges from about 700 nm to 1 mm. The energy of a photon can be calculated using the formula E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. This fundamental relationship explains the significant energy differences between UV and IR photons.

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?
 
Physics news on Phys.org
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?
 
Thank you. I will give that some thought.
