A sheet of glass having an index of refraction of 1.52 is to be coated with a film of material having a refractiveindex of 1.75 such that green light with a wavelength of 525 nm (measured in vacuum) is preferentially transmitted when white light is incident normally on the film. What is the minimum thickness of the film that will achieve this result

A55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. knowing that the plane has a speed of 550 km/h at point a, and the pilot experiences weightlessness at point c (i.e., the normal force from the seat bottom is zero), determine (a) the deceleration of the plane, (b) the force exerted on her by the seat of the trainer when the trainer is at point b.
