4.10 - Polarisation
- 11.5.1
- Polarised wave- A transverse wave
which is only vibrating on a single
plane
- Polarised wave- A transverse wave
which is only vibrating on a single
plane
- As light is reflected by a surface,
some of it is polarised but I don't
know how.
- Brewster's law
- When the angle
between the relfected
ray and the refracted ray
is 90 degrees,
polarisation is 100%
- When the angle
between the relfected
ray and the refracted ray
is 90 degrees,
polarisation is 100%
- Polariser- The first
thingy that makes the
wave one-planed
Analyser- the second
thingy which makes
the wave something
else, depending on
the angle between it
and the polariser
- Optically active
substance- solutions
which can rotate the
plane of polarisation,
e.g. sugar solution
- Some plastics become optically active
when put under stress (force), causing
different colours to appear when different
amount of force is applied to the plastic,
as they rotate differently.
