EPISODE 3
Electromagnetic Spectrum
ELECTROMAGNETIC SPECTRUM. It's all about the electromagnetic radiation spectrum - sounds complicated but this episode will make it all crystal clear. Dr Rob takes us through the elements of the EMS that we take for granted everyday then we delve into stories as fascinating as a crustacean with the most complex eyes on earth, just how television broadcasting works as well as fibre optics and medical imaging. Electromagnetic Spectrum 101 - Dr Rob takes us through the electromagnetic spectrum, explaining waves, frequencies, and colour. He tells us about the amazing things we can do with the spectrum, like broadcast episodes of Scope! Experiment - Remote Controlled Car We know what makes a remote controlled car go, but what makes one stop? Julia grabs the steering wheel and switches gears to find out what can stop a remote controlled car in its tracks. Mantis Shrimp Vision - The Mantis Shrimp is a truly astonishing animal, and to discuss it we join Justin Marshall, a biologist at the University of Queensland. Among other amazing qualities, this little critter can see ultraviolet light, and Justin explains why. Broadcasting - Just how will this episode of Scope end up being beamed out of television screens? We ask Jake Gillespie, Senior Broadcast Operator at Network Ten, who tells us all about broadcasting. Fibre Optics - What do thin glass tubes have to do with telephone conversations, television shows, and websites? We find out from Sean Manning, a physicist with the University of Adelaide, who fills us on how fibre optics work and how they are made. X-Rays - The electromagnetic spectrum doesn't just help us see things, it helps us see through things - people! We follow radiologist John Slavotinek from Flinders Medical Centre as he shows us X-rays, cat scans and MRIs. So join Dr Rob from gamma rays to x-rays and from microwaves to radio waves as he once again proves that the ordinary really does become extraordinary; under the SCOPE!
