As an admirer of thomas young, you perform a double-slit experiment in his honor. you set your slits 1.21 mm apart and position your screen 3.73 m from the slits. although young had to struggle to achieve a monochromatic light beam of sufficient intensity, you simply turn ona laser with a wavelength of 643 nm. how far on the screen are the first bright fringe and the second dark fringe from the central bright fringe? express your answers in millimeters.
a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.
in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
