Question

Which of the following electromagnetic waves has the shortest wavelength?
A. Infrared waves
B. Ultraviolet waves
C. Visible waves
D. Microwaves

Answer 1

B I've got a bit of a block on this, but I'm going to go with B for the shortest wavelengths. Also the highest energy and highest frequency. So, you can't SEE UV because it's outside the vis spectrum ... and thus more lethal when sun bathing.
Infrared is that nice warming feeling that you can get from a nice calm coal/wood/electric fire, when you stare into the embers. UV is when you put your sun glasses on.
I may have my frequencies and wavelengths in a twist ... i obviously hope not.
