Homework Statement
A pair of very flat glass plates, 7.41 cm long, touch at one end and are separated at the other end by a small piece of 44 gauge copper wire, 5.08×10−5 m in diameter. An air wedge is formed between the glass plates by this supporting wire. Light of wavelength 631 nm illuminates the apparatus from above. How many bright fringes will be seen from above, along the 7.41 cm distance?
Homework Equations
m* wavelength= 2nt
