Undergrad Spacing between three dimentional lattice planes
Thank you for the explanation. :) I think I understand, but the reciprocal lattice is, as you said, a little hard to understand(and visualize).- abhaymv

Undergrad Spacing between three dimentional lattice planes
What, exactly,does spacing between three dimensional lattice planes mean?Does it refer to the formula d=2*pi/(translation vector)? *I am an engineering undergraduate and this word is in my syllabus in topic crystallography.I was wondering what it meant? Also, can someone tell me in...- abhaymv

Undergrad Josephson Effect: AC vs. DC Explained
Just to be clear on this, DC josephson effect:Occurs when there is no ptential difference,and cuttent varies between -I to I AC Josephson effect:Occurs when the applied potential crosses a critical potential,Vc I am still unclear about what occurs in between the time when a small potential...- abhaymv

Undergrad Josephson Effect: AC vs. DC Explained
Its not homework.I didn't understand the lecture in my class.I have only bits of info.I think by what I understand, Both phenomenon occur when two superconductors are separated by an extremely thin insulator. Also that electons penetrate the insulators in pairs called cooper pairs. But I...- abhaymv

Undergrad Josephson Effect: AC vs. DC Explained
Hello, What exactly is the difference between ac Josephson Effect and DC Jsephson effect?When does each occur?What is the relevence of magnetic field here?In which cases are potentials applied?I tried to find the answer in the net,but couldn't find any satisfactory explanations.I have not begun...- abhaymv

How Long Does a Dropped Package Take to Reach the Ground from a Hot Air Balloon?
I think you'll have to take u as negative because balloon is traveling up.When it goes down, g is not -9.8m/s^2, but +9.8 m/s^2, because it is positively accelerating. 53=-11t+1/2*9.8*t^2. 53=-11t+4.9t^2 Its a quadratic equation! 4.9t^2-11t-53=0 Youll have to take the positive root. Now, you...- abhaymv
