Answer 1

Rebecca tells Tom that he is singing “off pitch.” Rebecca is referring to Frequency of sound.

Frequency is measured as the number of wave cycles that occur in one second. It is defined as the speed of the vibration and this further determines the pitch of the sound. This is usually useful for musical sounds where there is a strong waveform.
