Introduction (Part - 1) - Wave Optics, Physics, Class 12 Video Lecture

hello friends this video on babe optics
part one is brought to you by exam few
calm no more view from exam topics to be
covered in this lesson our introduction
hydrants principle reflection of plane
waves and refraction of plane waves
coherent and incoherent sources
interference Young's double-slit
experiment
diffraction resolving power of optical
instruments and polarization so like
always again here in this lesson we
would like to see why are we studying
wave optics in fact before that you
should know what are we going to study
in wave optics because in our previous
lesson that is ray optics we studied all
about mirrors lenses image formation and
their applications like the optical
instruments microscope telescope human
eye and all those things so there we we
studied about some of the properties of
light like for example the deflection of
light refraction of light so all those
stuff so here we say we are going to
study wave optics so I mean it sounds
little confusing right if you look at
the names that was ray optics and this
is wave optics that means again it has
something to do with the optical things
right the the tells for microscope they
all fall under those optical instruments
and Raj
so what are we exactly going to study in
wave optics so when you have this term
wave that means it has something to do
with wave properties so here in this
lesson we will talk about optics again
that is we will talk about reflection
right we'll talk about refraction of
light we will talk about some other
important properties of light which have
a lot to do with wave nature it is this
is the first and it is the start of the
lesson so things might look little
confusing for you but as we go ahead you
will see why is the lesson named wave
optics some other important applications
which we will come across when we leave
when we reach towards the end of the
lesson and your 3d glasses they are an
application or that is such an important
use where you find that one of the
properties of wave optics that is
polarization is put into juice your
cameras whether it is a photographic
camera or it is a camera for recording
3d views so those 3d photographic
cameras or maybe your car film this thin
film which you have on your car right
which protects you to do some extent
from sunlight right so these are some of
the things which are important
applications of some of the properties
of wave nature of light so now I have
introduced the term wave nature of light
okay so let us start the lesson without
discussing much about applications
because in this lesson we are going to
focus more on the theoretical aspect
than the practical aspect like in the
previous lesson we have already looked
at the practical aspect like the
microscope tennis form and all those
stuff so here we we need to focus more
on the theoretical aspect so the purpose
of this lesson it is to study the wave
nature of light so what is that wave
nature of light let us come we'll see
