0:00this Beetle has a very special trick its

0:02shell only reflects circularly polarized

0:05light and only in One Direction when we

0:08flip that polarized light in a mirror we

0:10see the opposite so what's happening in

0:13circularly polarized light the electric

0:15field components wiggle out of phase

0:17with each other and added together they

0:18make a twisty shape as the light wave

0:20propagates either to the right or to the

0:23left this beetle is one of the few

0:25animals on Earth that reflects this

0:26twisty light so when we look at it

0:28through a filter that only lets

0:30left-handed light through we can see all

0:32the bright colors but when we look at it

0:34through a filter that only lets

0:35right-handed light through it looks all

0:37boring and brown because that colored

0:39light is polarized only in the left-hand

0:41Direction not in the right-and direction

0:44scientists have known about this trick

0:45for over 100 years but just recently

0:47figured out that the Beatles can see

0:49left polarized light and many of their

0:51predators can't so it could be a way to

0:53see each other while hiding pretty

0:55bright idea
