World champion surfer Tristan

Kifer has out surfed them all [Tristan surfing]
- 00:08
professional surfers from every corner

of the earth or never the edge of a

at this point Tristan has only one [Tristan with a gold medal]
- 00:17
challenge left to overcome.
- 00:20
He desperately wants to beat the speed of
- 00:22
light his friends have advised him to [Friend advising Tristain not to beat the speed of light]
- 00:25
let this one go but Tristan has always
- 00:26
been more brawn than brains he'll just
- 00:29
have to learn this one the hard way
- 00:30
Tristan figures that beating light
- 00:32
should be right in his wheelhouse light
- 00:34
travels in waves and well so does he [Tristan surfing on a light wave]
- 00:37
unfortunately what Tristan doesn't know
- 00:39
about light could fill a beach house he
- 00:41
doesn't know for example that the speed
- 00:43
of light is a constant in other words it
- 00:46
travels at exactly the same speed [Wave of speed of light and shark moves along]
- 00:48
whether or not it's being chased by a
- 00:50
hungry shark that speed is 2.99 eight
- 00:53
times ten to the eighth meters per
- 00:54
second or if you're big on seeing
- 00:56
everything written out in long form well
- 00:59
here you go yes that.. This constant speed
- 01:02
is symbolized by the letter C Tristan
- 01:05
also doesn't know that the speed of
- 01:06
light is equal to wavelength time [Speed of light formula on a chalkboard]
- 01:08
frequency which are represented by these
- 01:10
symbols right here now wavelength and
- 01:12
frequency are not constant but they are
- 01:14
inversely proportional i.e when one gets
- 01:17
bigger the other gets smaller which is
- 01:19
how the speed of light remains constant
- 01:21
no matter what yet another thing about
- 01:23
which Tristan is clueless is the concept [Tristain standing alone in a room]
- 01:25
of amplitude imagine a calm ocean not
- 01:29
Tristan's cup of tea but stick with us this
- 01:32
is like the baseline of a wave now when
- 01:34
a storm's a-brewin and those waves are [Wave going through an ocean]
- 01:36
really rolling there is oscillation as
- 01:39
sometimes the top of a wave is higher
- 01:41
than our baseline and sometimes the
- 01:43
surface of the water is a bit below our
- 01:45
baseline roughly the same dealio with
- 01:47
waves of light the distance the height or
- 01:50
depth of a wave extends above or below
- 01:52
the baseline is the amplitude niche [Height shown for a wave]
- 01:56
looks like if this wave could use an
- 01:58
amplitude adjustment anyway, Tristan
- 02:00
armed with practically zero knowledge
- 02:02
but the heart of a champion is all ready [Tristan on a beach with his surfboard]
- 02:04
for the big day so close one can anyone
- 02:07
say rematch..
