This week's question comes from David Setter in Portland, Oregon. He asks: Does air temperature affect the speed of sound? Kim Strong, a professor of physics at the University of Toronto says the ...

WHEN IT COMES to cosmic speed limits, light gets all the attention. Its velocity in a vacuum, a tad below 300m metres per second, is an absolute upper bound on how fast anything in the universe can ...

New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make ...

This calculation depends on the speed of sound, which can vary in different environmental conditions, such as air composition or temperature. For example, there could be a difference of almost 10% ...

Lower-pitched sounds travel more slowly on Mars than higher-pitched ones, according to new data from NASA's Perseverance rover. When you purchase through links on our site, we may earn an affiliate ...

On Mars, the speed of sound depends on its pitch. All sound travels slower through Mars’ air compared with Earth’s. But the higher-pitched clacks of a laser zapping rocks travels slightly faster in ...
