Homework Statement
dear revered members,
please find the attached image for the topic interference in thin films due to relection.
Homework Equations
my questions are
1) angle between the incident ray or reflected ray or refracted ray is called angle of incidence, angle of reflection and angle of refraction, as the case needs. so <AON is angle of incidence. how <ACN is angle of incidence? because CN is normal line and AC IS POINT OF CONTACT, then how it is angle of incidence?
is there any geometry involcd in it?
ANY HELP IN THIS REGARD WILL BE GREATLY APPRECIATED, REVERED MEMBERS
