Question

A piece of fine fiber with a diameter of ?=6.9 ?m is used to prop apart the edges of two perfectly flat 3.1-cm-longpieces of glass (see diagram). When the setup is illuminated from above with light of wavelength ?=630 nm, an interference pattern of alternating bright and dark bands will be seen in the reflected light. If the setup is viewed from high above, how many dark bands will be seen?

A piece of fine fiber with a diameter of D = 6.9 µm is used
to prop apart the edges of two perfectly flat 3.1-cm-long
pieces of glass (see diagram). When the setup is illuminated
from above with light of wavelength 1 = 630 nm, an
interference pattern of alternating bright and dark bands will
be seen in the reflected light. If the setup is viewed from
high above, how many dark bands will be seen?
number of dark bands:
