Which of the following is an electromagnetic wave of energy?
a. wind
b. lightning
c. natural gas
d. ultraviolet light

Wind . . . moving air, has kinetic energy;  not a wave at all

Lightning . . . a pile of too many electrons falling over and pouring
                    down to either a cloud or the ground;  not a wave at all

Natural gas . . . a substance that is easy to burn in air and releases
                       a lot of chemical energy in the form of heat when you
                       burn it;  not a wave at all

Ultraviolet light . . . A wave, as well as an an electromagnetic one.  yay x 2.
                              Carries energy.

The rearrangement of particles in a physical change. hope this
