AI Thread Summary
Electromagnetic radiation in the ultraviolet (UV) region has shorter wavelengths, typically ranging from 10 to 400 nanometers, compared to infrared (IR) radiation, which ranges from 700 nanometers to 1 millimeter. The energy of a photon is 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. Since UV radiation has shorter wavelengths, it corresponds to higher energy transitions than IR radiation. Understanding these differences is crucial in fields like chemistry and physics. This knowledge aids in grasping the fundamental principles of energy transitions in electromagnetic radiation.

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.
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
