Sound is a form of energy. It is that form of energy which makes us hear. Sound wave is a vibratory disturbance in a medium which carries energy from one point to another without there being a direct ...
Though many people may hear “Doppler Radar” as tool for tracking weather systems, it is used for much more and has roots in science dating back generations. The Doppler Effect, as it is known, is also ...
Radar is quite spectacular in telling us exactly where rain is falling by pinging precipitation with radio waves! Our weather radar can determine more than just a storm’s location, but its movement as ...
Imagine you're at the train station, waiting to catch the northbound train. It's a quiet evening. You hear a horn sound in the distance, but it's the express coming from the opposite direction, not ...
The Doppler effect has helped us measure the world around us, from the movement of stars and clouds to sound frequencies. Gillian Isoardi from Queensland University of Technology explains how it works ...
A video of scientists dropping ice into a really deep hole has gone viral because of the wobbly cartoon-spaceship sound the falling ice makes. Princeton University geochemist John Andrew Higgins ...
G'day, Dr Karl here. Now most of us know that some bats find their way around using sound. This is called echolocation, and we've known about it since the 1930s. But just recently we discovered that ...
Physicists have generated a lot of excitement in recent years by dreaming up specially structured materials with novel applications like invisibility cloaks. What’s more, some of these “metamaterials” ...
A team including researchers from The University of Manchester’s National Graphene Institute (NGI) has revealed that sonic boom and Doppler-shifted sound waves can be created in a graphene transistor, ...
