PHY 1611L Lecture 2: lab 2- density

The table below summarises the results of an experiment in which the intensity of an X-ray beam was measured using a dosimeter. Metal alloy plates of identical composition but different thicknesses were placed between the source and dosimeter for different measurements.

What was the first experiment to show that light is a wave?

Data table 2 shoes data taken in a free-fall experiment. Measurements were made of the distance fall(y) at each of four precisely measured time. Complete the table
