Waves

• Wave length $\lambda =\frac{v}{f}$

  • $v$ is the speed of the wave
  • $f$ is the frequency of the wave
  • $\lambda$ is the wave length

• A wave form istodo

• A wave function istodo

Sine Wave

A sine wave (or sinusoid, symbol: ∿) is any function of the form $f(t)=A\sin (\omega t+\varphi )$, where: - $A$ is the amplitude - $\omega$ is the angular frequency (in $rad/s$) - $\varphi$ is the phase shift (which moves the wave left or right on the time axis) - $t$ is the time - $\sin$ is the sine function
