What is the unit symbol of wave speed?

Hz
m·s⁻¹ (correct)
m/s
m/s²

What is the definition of wavelength?

The distance between two successive crests or troughs of the wave (correct)
The time taken for one complete cycle of the wave to pass a given point
The distance a wave travels per unit time
The frequency of the wave

What is the relationship between frequency and period?

Frequency is equal to period
Frequency is half of period
Frequency is the square of period
Frequency is the reciprocal of period (correct)
