Waves & Electronic Radiation

BOCES4Science

In this unit of study, students create and revise their own models of how light travels, is reflected, absorbed and transmitted. Students contrast white light with the light from a laser pointer. Students learn about frequency, wavelength, and the energy of a wave by contrasting the properties of light from a laser with those of the light from a flashlight or a light bulb. Students also integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.
