17 group i contains x- and y- components of the electric field and group li contains the type of polarization of light. group i group ii p. e, = cos(øt+ +kz) v2

You can check the states of polarization of a wave by very simple methods.I am attaching some image.In the first page a table is given if you can remember it then you can tell the ...

see attached

if in both wave phase difference is π/2 then they are circularly polarized

if phase difference is 0 or π thrn they will be linearly polarised

see this

c is the answer
