• Part A Light of wavelength 600 nm passes though teo sits separated by 0.21 mm and is observed on a screen 15 m behind the sits. The location of the central maximum is marked on the screen and labeled y 0. Al what distance, on eiher side of y 0, are the m1bright inges? Express your anewer to two signincant nigures and incude the approprate unite. 43 mm v Correct • Part B A very thin piece of glass is then placed in one st. Decause light avels slower in glass than in air, the wave passing through the glass is delayed by 50 x10 in comparisorn to the wave going hrough the other sit. What fraction of the period of the light wave is is delay? Express your anewer uning two significant figures. At/T 025 v Correct • Part C With the glass in place, what is the phase difference Ad between the two waves as they leave the sits? Express your answer to two signincant ngures and incude the approprtate units. O I ? rad
