Measuring Your Light Speed – Mark 4:21-25
Measuring Your Light Speed – Mark 4:21-25 By Pastor Lee Hemen November 15, 2009 AM I loved physics in school, especially the labs. It was fascinating to set up experiments. One of the labs we had to do was measure how fast is the speed of light. The speed of light is approximately 186,000 miles per second or exactly 299,792,458 meters per second. The web site instructables.com teaches you how to measure it in your kitchen using a large bar of chocolate, a microwave, and a metric ruler. You take the turntable out of the microwave, place the chocolate bar, usually only three squares of a large bar, inside on a paper plate, and turn the microwave on high and wait for pools of melted chocolate to form. Zap the chocolate for about 40 to 50 seconds. Then carefully take the chocolate out and measure between hotspots with the metric ruler. When you measure between hotspots it represents the half wavelengths of light. You multiply this number by two, and then multiply that answer by the freque...
