Two identical microscope slides made of glass (n = 1.50) are stacked on top of each other. The slides are 8.00 cm long and are in contact at one end; at the other end they are separated by a piece of paper. You illuminate the slides from above with monochromatic light that has a wavelength in air of 565 nm. The spacing between the interference fringes seen by reflection is 1.30 mm. (a) Find the thickness of the piece of paper. (b) What would be the spacing between fringes if the space between the slides were filled with ethanol (n = 1.36) rather than air?

Question
Two identical microscope slides made of glass (n = 1.50) are
stacked on top of each other. The slides are 8.00 cm long and are in contact
at one end; at the other end they are separated by a piece of paper.
You illuminate the slides from above with monochromatic light that has
a wavelength in air of 565 nm. The spacing between the interference
fringes seen by reflection is 1.30 mm. (a) Find the thickness of the piece
of paper. (b) What would be the spacing between fringes if the space
between the slides were filled with ethanol (n = 1.36) rather than air?
