In this video resource from the Shedding Light series, science teacher Spiro Liacos introduces students to waves in general, and then takes a detailed and entertaining look at radio waves, microwaves,...
The study of transparent isotropic objects under polarized light, with demonstration of methods and instruments. Application to macroscopy and microscopy. Acquaintance with polarized light and interference...
Shows techniques used to produce polarized light, illustrating its characteristics and showing its utility for scientific and industrial purposes in the fields of engineering, geology and biology.*
Observes the behaviour of light in experiments involving black body radiation and the photoelectric effect. When the observations are analysed from the point of view of Maxwell’s model of light, it is...
Six-part documentary series exploring the concepts of physics from familiar theories, such as Newton’s Law of Gravity, to the latest in scientific research, like string theory and M-theory. By connecting...
Uses everyday examples, laboratory demonstrations and molecular graphics to explore polarisation as a wave phenomenon. Covers: generation of photons of light; photons polarised at right angles; conductors...
Explains the basic processes of photosynthesis and respiration and introduces their chemical equations by means of computer animation, location footage, diagrams and equations. Demonstrates an experiment to...
A discussion considering the properties and theories of light and how their study led to the special theory of relativity. Einstein’s mass-energy relation is also discussed.
Discusses interference or superposition, a property of waves. Covers: interference of waves in water; Young’s twin slit experiment; colour of soap films; coherent and incoherent light; Newton’s rings,...
Deals with the impact of light’s destructive qualities on two materials, dyes and polymers. It shows how industry monitors the problem with the help of the International Wool Secretariat at Ilkley (dye...
