Re: Speed of Light
more specifically 2.99792 x 108. I think in the book they use this (more sig figs) than 3.0 x 108

Re: Speed of Light
I did some research behind it, and some sources are claiming that recent studies show light doesn't always travel at the speed proposed by Einstein's theory. However, for the purposes of this class the speed of light is assumed to be constant.

Re: Speed of Light
You should treat it as a constant in any sort of calculations done for this class. I’m sure for higher level chemistry this would be different, but at this point I wouldn’t worry.

Would it be advisable to calculate using 2.99792 x 10^8 on the exams? I'm not sure when to apply significant figures - either throughout the problem or just for the final answer.
Re: Speed of Light
For the purposes of this class the speed of light probably will always stay the same. Though I think in certain mediums like water or glass the light of speed can change.

Re: Speed of Light
Just wanted to add that the speed of light is constant throughout the entire electromagnetic spectrum (~3.00 * 10^8 m/s)

Re: Speed of Light
It's assumed to be a constant and from my knowledge I believe we will be given the constant.
Re: Speed of Light
Will we be provided all of these constants/equations during the tests, midterms and final?

I am sure that we will get a cover sheet with all of the constants/equations as we did on the first test on all future tests as well.

Re: Speed of Light
The speed of light is a constant, therefore it will never change. You can, however, convert it to other units if you wish, as long as all the correct units cancel out.

Re: Speed of Light
The speed of light is always constant, and we are provided the value during tests and exams so we can just use whatever value they give us
Re: Speed of Light
The speed of light is constant and will not change, there may be a more specific value, however, it is most commonly known as 3x10^8 m/s

Re: Speed of Light
I'm pretty sure that for this class, we treat the speed of light as a constant all the time.

Re: Speed of Light
light always travels at the same speed regardless of wavelength or amplitude. it is a constant.
