Waves
-- Help |
The graphing window displays a left moving traveling wave f(x-ct), a right moving traveling wave g(x-ct), and their sum u(x,t) = f(x-ct) + f(x+ct). Select functions f(x) and g(x) using the popdown menu at the bottom. Select what functions to draw on the graphing screen by means of the column of buttons at lower left. Animate using the [>>] key or by grabbing the [t] slider. Use the [>] and [<] keys to increase or decrease t by 0.01.
