A pair of narrow, parallel slits separated with 0.270 mm is illuminated by the green component from a mercury vapor lamp (λ = 546.1 nm). The interference pattern is observed on a screen 1.23 m from the plane of the parallel slits. (a) Compute the distance from the central maximum to the first bright region on either side of the central maximum. 1 Your response differs from the correct answer by more than 10%. Double check your calculations. mm (b) Compute the distance among the first and second dark bands in the interference pattern. 2 Your response is within 10% of the correct value. This might be due to round off error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize round off error. Mm
If a car travelling at 30m/s will skid 18.00 m when its brakes lock and the car slides, how far would it skid if it is travelling at 40 m/s when its brakes lock? (This question is typical on some driver's license exams. Note: 10 m/s = 22 mph)
