Electromagnetic Spectrum

True or false: as you move along the spectrum, radio to gamma waves, the wavelengths decrease in size (get smaller)

• true
• false

High frequency waves have _________ wavelengths.

• varying
• long
• the same
• short

The distance between two crests or two troughs of a wave is called:

• frequency

• amplitude

• wavelength

• hertz
