Radio waves are electromagnetic waves and as such travel at the speed of light. Waves emitted a century ago would be 100 hundred light years away. A light year is the distance light travels in one year. In one year light travels about 5.9 trillion miles. therefore the waves traveled about 590 trillion miles in a century.
Answer:
C. Low-frequency seismic waves cause more ground acceleration than do high-frequency waves.
Explanation:
Low-frequency seismic waves covers more distance as compared to high-frequency waves because high frequency wave provide more energy to the medium while low frequency waves supply less energy to the medium so which makes the wave to go further. Lower frequency waves "penetrate" into a materials better, because energy particles having lower frequencies having less energy and they pass through the medium without interacting with the matter.
