Question: radiation? Why does electromagnetic radiation in the ultraviolet region represent a larger energy transition than does radiation in the infrafed region?

Answer: Ohh well have u ever heard of the plank's equation? E=hv=hc/w where E is the energy of the particle light(Photon) or the energy associated with one photon of radiation.. and v=frequency of that radiation.. c=velocity of radiation(light) w=wavelength of radiation.. as the wavelength of radiation increases from UV rays to Infrared rays,,, the frequency of radiation decreasea from UV rays to infra-red rays.. and hence, the energy associated with one photon of radiation decreases in the region from UV rays to infreared rays.
