In general it is best to conceptualize vectors as arrows in space, and then to make calculations with them using their components. (you must first specify a coordinate system in order to find the components of each arrow.) this problem gives you some practice with the components. let vectors a =(2,โ1,โ2), b =(4,โ3,0), and c =(โ2,1,6). calculate the following, and express your answers as ordered triplets of values separated by commas.

The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656(red) and 486 (blue). light from a hydrogen lamp illuminates a diffraction grating with 500 lines per mm, and the light is observed on a screen 1.50 behind the grating. what is the distance between the first-order red and blue fringes?
