Thank you We sneak world champion surfer tristan keifer has

00:06

out served them all professional surfers from every corner of

00:10

the earth Or never the edge of a sphere is

00:13

have tried and failed to beat him At this point

00:16

tristan has only one challenge left to overcome He desperately

00:20

wants to beat the speed of light His friends have

00:24

advised him to let this one go But tristan has

00:26

always been more brawn than brains He'll just have to

00:29

learn this one the hard way Tristan figures that beating

00:32

light should be right in his wheelhouse Light travels in

00:35

waves and well so does he Unfortunately what tristan doesn't

00:39

know about light could fill a beach house He doesn't

00:42

know for example that the speed of light is a

00:44

constant In other words it travels at exactly the same

00:47

speed whether or not it's being chased by a hungry

00:50

shark That speed is two point nine nine eight times

00:53

ten to the eighth meters per second Or if you're

00:56

big on seeing everything written out in long form well

00:59

here you go Yeah that this constant speed is symbolized

01:03

by the letter c tristan also doesn't know that the

01:06

speed of light is equal to wavelength times frequency which

01:09

are represented by these symbols right here Now wave length

01:12

and frequency are not constance but they are inversely proportional

01:16

iii When one gets bigger the other gets smaller which

01:19

is how the speed of light remains constant no matter

01:21

what Yet another thing about which tristan is clueless is

01:25

the concept of amplitude Imagine a calm ocean tristan's cuppa

01:30

tea but stick with us This is like the baseline

01:33

of a wave now when a storm's a bruin and

01:35

those waves air really rolling there is oscillation as sometimes

01:40

the top of a wave is higher than our baseline

01:42

and sometimes the surface of the water is a bit

01:44

below our baseline roughly the same dealio with waves of

01:47

light the distance the height or depth of a wave

01:51

extends above or below the baseline is the amplitude looks

01:57

like it this way I could use an amplitude adjustment

02:00

anyway tristan armed with practically zero knowledge but the heart

02:02

of a champion is all ready for the big day 00:02:06.04 --> [endTime] Close one eye and anyone's a rematch
