Light with a single wavelength is referred to as monochromatic (________ for "one color), "but light with many wavelengths is referred to as polychromatic.

Visible light

________ is only a small part of the spectrum.

channel of an FM radio station

The ________ is the frequency, measured in megahertz (MHz), at which it broadcasts.

units of meters

The term* Wavelength* refers to being measured in ________ or, for extremely small wavelengths, nanometers (nm, 109 m), picometers (pm, 1012 m) or angstroms, (1010 m), a non- SI unit.

frequency of electromagnetic radiation

The value represents the ________.

electromagnetic radiation waves

All ________ move at the same speed in a vacuum, but they differ in frequency and, hence, wavelength.

high frequency

Because the product of ν and λ is a constant, they have an inverse relationship- radiation with a(n) ________ has a short wavelength, and radiation with a low frequency has a long wavelength: ν↑λ↓ and ν↓λ↑.
