Standing Waves
Standing waves are formed by superposition of two waves having same frequency and amplitude travelling in opposite directions.
### Equation
$$y=2A\sin kx\cos\omega t$$
### Terminologies
- A → Amplitude of individual waves.
- k → Wave number.
- ω → Angular frequency.
### Conditions / Special Cases
- No net energy transfer occurs.
### Usage
- Used in string vibrations and air column problems.
