2. The Wave Equation If you take a long string and shake one end, you will create a disturbance. Guess what, with that simple shake you've made a wave pulse, which travels along the string.

Physicists noticed that waves in pieces of string, sound waves in the air, and electromagnetic waves all seem to follow the same laws of wave motion. So they invented an equation called the ...

Video: Equations that rule the world The Pythagoreans figured out what makes strings sound harmonious THE alarm rings. You glance at the clock. The time is 6.30 am. You haven't even got out of bed ...

The enlarged differences indicate that TS-CPML has a better absorbing performance than the conventional CPML implementation of the second-order wave equation. ### See the article: Fang X, Niu F. 2021.
