I love this app ❤️ I actually use it every time I study.
Alternative transcript:
to direction whered in Transverse, they move perpendicularly. Longitudinal waves do not have amplitude or wavelength but transverse do. Longitudinal waves have compression and rovegraction but transvese don't. wavelength
