This film demonstrates the measurement of the speed of light in both air and water using experimental setups. The first experiment involves measuring the time it takes for light to travel a known ...

San Jose, Calif. – Immersion extends a stepper lens' depth of field by beaming the light through a layer of water on top of the wafer. The liquid changes the refractive index, markedly boosting both ...

Explores the principles of light, reflection, and magnification through hands-on experiments. Children observe how a magnifying glass focuses sunlight to create heat, examine the effects of light on ...
