a. Consider a Michelson interferometer with one fixed arm andone moveable arm, both of length 5 m. If 300 nm laser light isshown through the device, what percentage change in the length ofthe movable arm will shift the detector from constructive todestructive interference?
b. A telescope is looking at a 2 star system. If the stars are1.5 x 10^13 m apart and 9 x 10^16 m away, how big does thetelescope opening have to be to resolve the two stars?
c. If red light (lambda = 800 nm) and violet light (lambda = 400nm) are alternately shown through a slit with width 1 mm, find thedistance between the first minima for these different lights on ascreen 5 m away.
