Question

The period is the time required for a wavelength to pass a stationary point. t or f

Answer 1

Answer: the time taken for two successive crests (or troughs) to pass a fixed point

Step-by-step explanation:

We call this time the period, and it is a characteristic of the wave. The symbol T is used to represent the period. The period is measured in seconds (s). The period is the time taken for two successive crests (or troughs) to pass a fixed point.
