could you please use the math tags from now on? click on a LaTeX image and it will show you the code that produced it.
yea. i haven't seen an inverse square law FOR light, though, but i graduate high school saturday. i've used them for electric force/fields and gravitational force/fields.
can you explain this bit?
so, are you saying the amplitude is equal to the force of gravity? could you show this rather than assume it? also, i wouldn't use a small "a" for amplitude as it can easily be construed as aceleration.
how did you determine it?
