ALREADY PASSED
thermal radiation - =spectrum of radiation produced by an opaque object that depends only on
the object's temperature; sometimes called blackbody radiation
Strong Force - =holds atomic nuclei together
Speed of light - =300,000 km/s
Rest wavelength - =the wavelength of a spectral feature in the absence of any Doppler shift or
gravitational redshift
refracting telescope - =A telescope that uses lenses to gather and focus light
reflecting telescope - =A telescope that uses mirrors to collect and focus light
radio waves - =light with very long wavelengths (and low frequencies)
Photon - =individual particle of light
Microwaves - =Light with wavelengths in the range of micrometers to millimeters. are generally
considered to be a subset of the radio wave portion of the electromagnetic spectrum.
Light-collecting area - =are of primary mirror or lens that collects light in a telescope
Isotopes - =forms of an element that have the same number of protons but different numbers
of neutrons
