Monochromatic light illuminates two, narrow parallel slits. The centres of the two slits are 0.800 mm apart. An interference pattern forms on a screen 50.0 cm away. The fringe separation on the screen is 0.304 mm. Find the wavelength λ of the light.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
