Light reflects off of the medium at a angle to which it initially struck the material.

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

This is the number of complete movements of a wave per second.

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?
