I Question on an infinite summation series
Is the infinite series ##\sum_{n=1,3,5,...}^\infty \frac {1} {n^6}## somewhat related to the Riemann zeta function?The attached image suggest the value to be inverse of the co-efficient of the series.Is there any integral representation of the series from where the series can be evaluated? -

Question about a problem from 'Optics' by Eugene Hecht
That's what I mentioned in the statement. I found the least thickness to be 173 nm. So 25 nm is not enough to produce fringe pattern? What about if the width was 200 nm. Would that be enough to answer the question(what about the order of the fringe)?- phymath7

Question about a problem from 'Optics' by Eugene Hecht
As the value of cos##\theta_{t}## comes out to be greater than 1 so I tried to calculate the minimum value of d the thickness of film which turned out to be approximately 173 nm. Which clearly reflects the fact that the thickness is not enough to produce the fringes. Am I right? Is the question...- phymath7

I Infinite value of amplìtude of an undamped driven oscillator at resonance
I wonder how this can be explained by the work-energy theorem.- phymath7

I Infinite value of amplìtude of an undamped driven oscillator at resonance
So if we set the damping constant ##\beta=0## that is if we consider an undamped oscillator the amplitude becomes infinity! What is the physical meaning of this phenomena? As we know energy fed into the system is proportional to ##A^2##. So does this mean that an infinite amount of energy is...- phymath7

B Is the Speed of Light Consistent Across Rotating Reference Frames?
Does the 2nd postulate of special relativity imply that if I shift the origin of a co-ordinate system to make another(without rotation),only then the speed of light is constant in both reference frame but so is not true when I do the shifting with rotation?- phymath7

About critical damping resistance of a ballistic galvanometer
Did you write the explicit relation between ##\lambda## and ##R_2## ?Do you see how complex this one? I am afraid that it's beyond my (and even for those who are more advanced) capability to do the fitting.- phymath7
