comment Why do we use the index of refraction for yellow light?
In addition to model with the Abbe coefficient, you may use refractiveindex.info as a source of wavelength dependacy. The difference to the model won't be large in the visible regime

comment Does Earth's Rotation Affect Its Shape?
Thank you for the answer and welcome to physics SE! The question explicitely asks about the influence of rotation on the shape of the earth. Please elaborate on this topic. Otherwise this may fail to answer the question.

comment How does one align a laser using two adjustable mirrors?
Could you elaborate on the laser alignment. Maybe sum up the key points in your link. In case there is link rot, your answer will no longer be useful. It seems a nice resource.

comment Why do most metals appear silver in color with gold being an exception from a scattering and EM viewpoint?
I enjoyed the sequel of this topic. As @Gruenkohl pointed out the "skin depth axis should say nm not µm".

comment Can you punch a hole in an A4 sheet of paper with your hand?
A newspaper has a low bursting strength. The line where it is folded is a structural weakness. The trick even can be done with a newspaper in free fall - an archievement even for an martial arts artist.

comment Optimal size of a windmill for a given windspeed
Welcome to Physics SE! This is a common homework problem. Since length $r$ of blades is your concern, why not put it in the title? Here on PSE you find questions for "blade and wind" like a windmill with weighted blades or the homework hint for the work of a windmill. What have you tried to solve the problem?

comment Only transverse photons are gauge-invariant (Peskin page 298)
Welcome to Physics SE! You can add math inside Dollar brackets just like in LaTeX: $A_0$ It's called MathJax here. Others could understand your question if you included the equation.

comment Partial Pressure - Which solution is right?
Welcome to Physics SE! I edited your post to add the nice layout of the equations. MathJax on this website makes math more readable. Check it out! To learn it, just hit the edit button on your post and see, that the math simply is marked up using a dollar. SI units are separated by a small blank with "\,".

comment Does Earth really have two high-tide bulges on opposite sides?
Welcome to Physics SE! You provided interesting information, but did not answer the question "Does Earth really have two high-tide bulges on opposite sides?" You guessed it has something to do with tectonitc plate movements, but did not give a reference to underline it. Anyway welcome :)
