Introduction

High-speed photography deals with capturing on film physical phenomena that can not be seen under normal conditions. The easiest and most economical way of doing this is with high-speed electronic flash or stroboscope. A flash duration as short as 30 millionths of a second for electronic flash units or 5 μs for a stroboscope are possible (but not in our lab) and can stop rapidly moving objects.

Students will learn how to capture images of objects or phenomena that occur at high speeds. They will learn how to use remote triggering systems with sound or light triggers to trip electronic flash units to freeze the action. Or they may use strobe photography for analyzing phenomena over a longer period of time.
