light reflected from air wedge formed by glass plates.

I am having a bit of trouble with a problem in a algebra based physics course. Any help would be appreciated. Here goes: When blue light (wavelength 589nm)is reflected from an air wedge formed by two flat glass plates, the bright fringes are 0.6cm apart. 1)How thick is the air wedge 5.0cm from the line of contact of the pl ...continues

Parallel plates

Imagine that you would like to design a parallel plate capacitor that could store 1 J of electrical energy in the electric field between its plates when connected to a 1.5 V battery. Imagine that you can arrange things so that the plates can be separated by a distance d as smal as 0.5 mm. (Hint argue that the electric field str ...continues

Nested Shell Capacitor

a) Argue that the energy stored in the electric field of such a capacitor is Ufield=1/2CVo2, if Vo is the potential difference. (Hint: Argue that between the plates, the field strength is EVo/d, where dRo -RI is the distance between the conductors. Use the equation for the capacitance of a nested sell capacitor ...continues
