Interference Flashcards
Path difference, Phase difference and interference
In interference pattern what is than name for each striation?
Central maxima- centre bright node
1st order maxima- bright node either side of the centre
2nd order maxima- bright node either side again and further out
etc…
What is the relation between n and n+1 maxima (adjacent bright lines of interference)?
2π phase difference or λ
Name the equation derived from young’s double slit experiment.
λ=(ax)/D
where a is the displacement between slits
x is the displacement between maxima
D is the displacement between slits
What are nodes and antinodes?
A node is a point of zero displacement on a stationary wave
An antinode is the point of maximum displacement.
What is the de broglie equation?
λ=h/p
where p is momentum
What is the de broglie wavelength?
The wavelength of any particle of a known mass and velocity
