The students keep the spring stretched by a constant amount so that its length remains the same. The students then produce two new waves, wave X and wave Y. Wave X has twice the frequency of the original wave. Wave Y has half the frequency of the original wave. How do the wave speeds of wave X and wave Y compare to the original wave

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?
