A diffraction grating is 1.68 cm wide and contains 2400 lines. when used with light of a certain wavelength, a third-order maximum is formed at an angle of 17.9°. what is the wavelength (in nm)?

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
