View OChemch3partII.ppt from CHM 241 at Thomas Nelson Community College. Bellringer – 2 mins to hand in. Properties of Waves The properties that waves have depend on the vibrations that produce the waves.For example,if you move a pencil slowly up and down in a bowl of water, the waves produced by the pen-cil’s motion will be small and spread apart. Other sources include fire, stars and man-made light sources such as light-bulbs and torches. It was getting dark outside, so she stayed near the bonfire. Sometimes we forget about all the factors that go into lighting a portrait. He explained that, like the bonfire, the sun burns gasses to emit (or give off) light. The wave model of light describes light as a wave that travels through empty space. The word “wavelength” is used to express the wave or undulating property of light. Discuss how wave motion arises and its measurable properties, noting the conclusions of Young’s double slit experiment.
