Is there a difference between 'pitch' and 'frequency'?

Answer 1

Yes.

Pitch is the perceived fundamental frequency of a sound.
Frequency is the measurement of the number of occurrences of a repeated event per unit of time.

Example:
The frequency of the standard pitch A above middle C is usually defined as 440 Hz, that is, 440 cycles per second and known as concert pitch, to which an orchestra tunes.

Answer 2

In addition to "pitch" being restricted to the range of hearing, pitch is also restricted to specific engineering units.

These units are usually "oscillations per second".

Although you are probably also using the same engineering units for frequency, it is not necessary to do so. Frequency is merely how often. For example the frequency of days in a year is 365.242.

365.242 "rotations of the earth/orbit around the sun."

Answer 3

The frequency of a sound determines its pitch

Answer 4

Nah. I'd say they're basically the same. Just that pitch is used in a different context, i.e. musical notes, but in that context, it means frequency.
pitch = frequency
volume = amplitude

Answer 5

yes
pitch is the maximum amplitude u reach and
frequency is the number of times u reach that amplitude in a second
