This exhibit will be a working 2 foot diameter parabolic radio telescope that will scan the sun. Data will be recorded with a chart recorder. Visitors can use the telescope and take the chart recording home with them. They can also place their hands between the dish and the focal point. They will see a rise in intensity on the chart recorder.
People emit radio waves.
The emission process is thermal. Visitors synthesize the entire process of detecting radio waves from space. Visitors participate in science by using a radio telescope. Exhibit Group 3. This exhibit would allow visitors to observe and graph continuum and spectral line radiation from light sources and radio sources.
