I am not 100% sure but I believe reflection is an absorption and re emission however I would consult with your professor because some tests and texts assume a photon bounces rather than becomes re emitted or phase shifted. Also Hyperphysics has some great overviews on the concepts ! I hope this...

True! I would like to point out I read the formula wrong and its if r> or =1 then it diverges. Taking a look at the problem again, if we take the highest power in the numerator and the denominator, like in my last step, we get it going to 1. That means it does diverge by the divergence test...

Homework Statement The problem is part of a review and we are only to determine if the series converges or diverges by any test, and state the test. ##\sum_{n=1}^\infty(\frac{k}{k+1})^k## My work so far I know that the root test gives an inconclusive answer and from there I moved...

Oh wow thank you I guess I was over thinking this.

A fish looking straight up to the surface of a pond receives a cone of light filled with images. This bright field is surrounded by darkness. Explain what is happening and compute the cone angle. No given data but ##n_w=1.33## No give equations but I anticipate Snell's law and maybe the...

I am still unsure of what I did wrong but after retyping it today I got the same answer. So I don't have to do any other operations even though it is in improper form? I just want to make sure that there wouldn't be a different result if preformed a different way.

Homework Statement evaluate $$\int_0^1\frac{Ln(x)}{1+x}\,dx$$ Homework Equations I know the way to solve most improper integrals; replacing 0 or the bound causing the issue with a variable and have the limit of the integral as the variable goes to infinity. My question is using...
