White light is passed through a diffraction grating that has the spacing between the slits of 4x10^6m. on each side of the white central maximum, a spectrum of colors is observed. what is the wavelength of the light observed at an angle of 7.00° in the first-order bright fringes?

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
