1. Why does electromagnetis radiation in the ultraviolet region represent a larger energy transition than does radiation in the infrared region?
-I think it has something to do with the frequency or wavelenghts but i have no idea.
2. The wavelength of light is 310 nm. Calculate its frequency.
- I have no idea how to do this one
3. What is the wavelength of electromagnetic radiation if its frequency is 3.2 x 10 (-2) Hz?
- What??????
I'm so confused
Someone help me out?
Thanks if you can help

1. Electromagnetic radiation, in this case, refers to the energy emitted by an electron that transitions to a lower energy level. Because the frequency of radiation is directly proportional to its frequency, and ultraviolet light has a greater frequency than infrared, it represents a greater amount of energy.
2. and 3. For any wave, the formula λ = fv holds true, where λ is wavelength, f is frequency (normally in units of Hz, which are equal to s^-1 or "inverse seconds"), and v is velocity. For any electromagnetic wave (including light), the velocity is c = 3 x 10^8 m/s, the speed of light.
