Wave properties and the electromagnetic spectrum

Use this for “Which color of light has the longest wavelength?” and “How many waves of green light fit in one millimeter?”

Use this for “A wave on a rope has a frequency of 2 Hz and a wavelength of 1.5 m. How fast does it travel?”

Use this for “Order these waves from longest wavelength to shortest.”

Use this for “How do the vibrations compare for a louder sound versus a higher-pitched one?”

Use this for “Why are digitized signals a more reliable way to store and send information?”
