When I got it from my friend she was told it was a type of yucca. I've looked up yucca trees and can't find one that looks like mine. I'm kind of doubting that its a yucca now. If someone who has experience with this sort of thing would contact me directly, I could e-mail a picture of the plant and you could e-mail me back! Thank you for any help!

You know how they say objects that we are viewing in space are an older image of the objects current state due to the light travelling such a long distance. What if we viewed the eath from another part of space , and just say we had the technology to highly zoom in on the earth , would the image of dinosaurs still be out there , going through space , and is our image being projected through space?

Regarding the typical electromagnetic radiation (EM) produced by a current flowing through a straight power line: What is the wavelength (or frequency if you prefer) of this radiation. Is there a function with the variables being: 1) the distance you are from the actual wire (since the intensity dissipates at a rate proportional to the distance squared) and 2) if necessary, the voltage and wattage of the current. I would assume that the EM is in the form of radio waves (and even possibly slightly higher frequency microwave radiation), but I would like to prove this. My goal is the proof, in the form of a function.
