Regular(Specular) and Diffuse Reflection Video Lecture | Science for Super TET

hello again and welcome to 5-minute
physics
today's topic is reflection specular and
diffuse the first kind of reflection is
specular to put it simply it's a flat
mirror or another flat surface and when
light rays hit it like so they're
reflective at exactly the same angle as
from which they came so let's say that
this one here came and hit the mirror at
a 45 degree angle it'll be reflected off
of the surface at a 25 degree angle so
the mirror is flat and they're reflected
like that perfectly reflected all of
them are the same in diffuse reflection
it is by no means the same the
reflection is erratic
so you you'd have this ray coming in
this way and it would be reflected
upwards and this one would be reflected
sideways and all the rays are moving in
different directions because the surface
is rough it's not straight it's not flat
nothing is reflected in the same
direction so an example of that would be
some household objects the anything
really in it specular reflection can be
found in smooth water glass typically
cut gemstones basically anything that is
shiny and what we would normally say
reflective in a non-scientific sense and
diffuse reaction to few sorry
reflections would apply to anything else
any plastics or fabrics would that's why
this mirror you have in your bathroom is
nice and shiny while your new t-shirt is
not because your new t-shirt is
reflecting light in a bunch of different
directions instead of just one so you
can't tell that it's reflecting as much
light that's basically it for this so
I'll see you again next time and thanks
for watching
you
