I'm struggling with section a. This is my calculation: The expression remains depend on the variable t, while in the answer is a concrete number:

according to the answer, d is half the distance between two diagonally positioned atoms, which in the figure is the line segment between one atom to the red arrow. I don't see why this segment is the answer to what I'm being asked about?

but if the interatomic separation is L, and what I'm being asked about is the distance between those parallel lines, isn't d should be equal simply to L?

according to the figure, it's look like d is the distance between the center of two adjacent atoms, and so it should be simply L. I don't understand what d represents in the figure. that's the solution: Even if d is half the distance between two adjacent atoms that positioned diagonally (I...

There is a difference in the questions (amount, difficulty) between fundamentals of physics extended 11th edition and principles of physics 11th edition? And both textbooks treat the theory the same in terms of derivations?

projects and seminars offered in any physics program but I didn't knew that these are count as research to the degree that US universities would care about. I thought that research is all about exploring stuff that has never been explored before including publications, or at least contributing...

I'll consider it. thanks. do you know about international students who participate in physics internship in the US? if it possible maybe I'll check out for some opportunities during the summer like summer school of some sort. my only concern is that it might be very expensive. what do you think...

Hi my name is Idan. I plan to study for a physics Bachelor at Israel, my homeland. although is way too early I'd like to proceed towards higher education as well, particularly in the US. The problem is that in Israel there is no physics internships and research projects offered for students at...
