two waves interferences


angle of incidence for bright ring fringe


Caution
Fill in all input cells.
Choose all parameters unit.
The plate material is supposed to be a dielectric. Consequently there is an air/glass and a glass/air reflection introducing an additionnal phase shift of p.
n can be either a value or the reference of a glass from the catalog.
All parameters are positive.

angle of incidence for bright ring fringe
lam : wavelength e : interferometer thickness n : refraction index of the interferometer k : bright fringe number ( counted from the center ) ik : angle of incidence for bright fringe number k
