Chapter 7 - Quantum Theory and Atomic Structure

Light

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

electromagnetic radiation

In a vacuum, ________ moves at 2.99792458×10 m /s (3.00×108 m /s to three significant figures), a physical constant called the speed of light (c):

Visible light

________ is only a small part of the spectrum.

frequency

The channel of an FM radio station is the _______, measured in megahertz (MHz), at which it broadcasts.

product of ν and λ is a constant

Because the ________, they have an inverse relationship- radiation with a high frequency has a short wavelength, and radiation with a low frequency has a long wavelength: ν↑λ↓ and ν↓λ↑.

electromagnetic radiation waves

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