Frequency and amplitude
frequency
Frequency works by how long the wavelengths are. a high frequency has a short amount of waves, a low frequency has a long amount of waves. This is how it looks:
amplitude
Amplitude is how loud or quiet something is. it does not matter how high or low the sound is. amplitude has another name, volume. Amplitude gets taller or shorter as a sound wave. If the wave is tall, that means it is loud. If the wave is short it is quiet.
see the image above? these sounds both have the same frequency but one is louder than the other.
