Question

Describe the experimental evidence and reasoning that led 19th century physicists to conclude that light has wavelike properties. In doing this, you should discuss at least one semal experiment, and explain what was known about the properties of light before the experiment, what key piece of evidence from this experiment changed physicists' understanding of light , and describe the new understanding of the physical nature of light that developed as result of this experiment.

Answer 1

The Electric Experiment by J.J. Thomson

J. J. Thomson was one of the great scientists of the 19th century; his inspired and innovative cathode ray experiment greatly contributed to our understanding of the modern world.

Like most scientists of that era, he inspired generations of later physicists, from Einstein toHawking.

His better-known research proved the existence of negatively charged particles, later called electrons, and earned him a deserved Nobel Prize for physics. This research led to further experiments by Bohr and Rutherford, leading to an understanding of the structure of the atom.

What is a Cathode Ray Tube?

Even without consciously realizing it, most of us are already aware of what a cathode ray tubeis.

Look at any glowing neon sign or any
