Can the amplitude of a wave be negative

WebExplanation: Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. WebThe instantaneous value of the wave function is a complex number, with both real and imaginary parts that can be either positive or negative. But by “amplitude” we mean the …
