scientists described light as a wave because the results of many experiments with light demonstrated that light behaves as a
wave. light is now described as having properties of both a wave and a particl
what is the most likely reason why this change was made?
enough scientists voted to accept the change,
data collected from many experiments could not be explained using waves
a well-known scientist published a paper that described light as a particle.
a single experiment's results demonstrated both wave and particle properties

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
