The frequency. Think of it like this. Imagine you two waves like this:
__ __
(A) l l__l l__l
_ _
(B)l l_l l_l
Wave A would be lower than wave B because wave A has a lower frequency, and thus is lower.
The difference in pitch.
high pitch is high frequency, low pitch is low frequency
In general, a low pitch is created by sound waves vibrating and having to travel down a lengthy object, while a high pitch only has to travel down a shorter distance
A triangle has high pitch.
High
The pitch of the sound.
pitch
high pitch is high frequency, low pitch is low frequency
pitch - how high or low a sound is volume - how loud a sound is
Yes
Its wavelength, or pitch. Sound is only vibrations in the air. If the wavelength of the vibration is low, then it will sound "high". If the vibration has a high wavelength, then it will sound "low".
