An air pocket is insrted between a plastic slide with an index of 1.42 and a glass slide with an index of refraction 1.61.
a. if we light 500nm, is the,light incident on the air stuck between the plastic slide and glass slide initially out of phase (destructive) at the edges or in phase (constructivity) ?
b. How thick is the air at the third dark ring from the edge?
c. if the air bubble is 5micrometers thick, how many dark rings do we see?
