Ok, and what is phase differential?

Hello all I know that polarisation of light can occur from reflection, and when the reflected ray is 90degrees from the refracted ray the relfected light is 100% plane polarised. So, my question is why is it that reflection causes polarisation of light? Thanks

Thanks :) so just to double check that I've understood, youre saying that intensity=power per unit area. And since power=energy per second, the factors affecting power (thus intensity) are both the frequency of the photons and the number of photons, right?

Have you tried resetting your memory on the calculator?

also i think i can say that there is no difference in whether you change a to rational or irrational, and there will always be two solutions, as it will always be some root but i don't know about non-real numbers, sorry.

x^a=b log[x](b)=a <--- [x] is base x log(b)/log(x)=a (1/a)*log(b)=log(x) log(b^(1/a))=log(x) b^(1/a)=x

OK, so i have a question about the nature of light, in the context of the photoelectric effect. So when photons are incident on a metal, given that they have a high enough frequency they can cause electrons to be emitted from the metal. Now i know that intensity of light is to do with the...
