Q
What thickness of film is needed to create constructive interference?
A
λ/4
1
Q
Define the variables from the equation:
nλ=d(xn/L)
A
n = integer of wave λ = wavelength (m) d = distance between slits (m) xn = distance between central fringe and selected fringe (m) L = distance between slits and screen (m)
2
Q
What thickness of film is needed to create destructive interference?
A
λ/2
3
Q
Gauss’ Law
A
The amount of electric field lines that pass through a surface is proportional to the amount of charge
4
Q
Gauss’ Law for Magnetism
A
The amount of magnetic field lines leaving a volume of space is equal to the number of magnetic fields enter a volume of space. Proving no monopole
5
Q
Faraday’s Law of Induction
A
A changing magnetic field will induce an electric field
6
Q
Ampere-Maxwell Law
A
A changing electric field will induce a magnetic field
