A three-dimensional region around a nucleus where an electron may be found is called a(n

• orbit
• circle
• orbital
• circuit

If an AM radio station broadcasts at 995 kHz, what is the wavelength of this radiation?

• 6.59 x 10^-28 m
• 1.01 x 10^-6 m
• 3.32 x 10^-3 m
• 301 m

Based on the picture, choose the best description of how wavelength and frequency are related

• As wavelength increases, frequency increases
• As frequency increases, wavelength remains the same
• As frequency increases, wavelength decreases
• frequency and wavelength mean the same thing
