Consider a 400 nm thick film of water (n-1.33) on plastic (-1.9). visible light is incident. on the film firom air. (25 pts) sketch this situation and clearly indicate the rays which are interfering with one another. (5 pts) a b. find three wavelengths that will be reflected brightly from the film. (14 pts) c. find three wavelengths that will be reflected very dimly, if at all, from the film.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
