Royal Institution Christmas Lectures

First light (1976x1)

Air date: Dec 01, 1976

Sir George Porter explores light's structure in this 1976 CHRISTMAS LECTURE packed with live demos. Have you ever wondered why the sky is blue or why sunsets are red? Porter explains how colour is created through light 'scattering' which John Tyndall discovered. Porter also demonstrates how light is made up of frequency, waves and molecules. He presents Thomas Young’s light source experiment on a grand scale using light and cameras.
