Light and Sound
Question | Answer |
---|---|
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 |
