First, you must find the wavelength of the laser. you shine the laser into the interferometer and then move one of the mirrors until you have counted 100.0 fringes passing the crosshairs of the telescope. the extremely accurate micrometer shows that you have moved the mirror by 0.03164 millimeters. what is the wavelength λ of the laser?

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..

prndulum needs thread, weight clock to time swings

god i hope this !
