Light and Sound

QuestionAnswer
electromagnetic radiation light
written as "c"; 300million m/s (all forms of light levels travel at this speed) speed of light
The 2 properties of light 1. wave-like 2. particle-like
the distance between 2 successive peaks of a wave; inversely related with frequency wavelength
the number of cycles of a wave that pass a specific point in 1 second; inversely related with wavelength frequency
the higher the ______________, the more __________ there is frequency; energy
a particle of electromagnetic radiation; "light quantum" the amount of energy this particle carries is directly proportional to its frequency & inversely proportional to its wavelength photon
longitudinal waves that travel by compressions and rarefactions in the air, water, or other mediums travels faster through solids than liquids, and faster through liquids than gas sound waves
sound requires this component in order to travel medium
this increases with higher temperatures, but decreases with higher density comes down to how the particles interact inside of the medium speed of sound waves
