What unit is used to express the distance of a wave's cycle?

Explanation:
The distance of a wave’s cycle is the wavelength, which is a spatial measure of how far the wave travels for its pattern to repeat. Because it is a length, the natural unit is meters, the standard SI unit for distance. That’s why meters is the best answer. Seconds would describe time per cycle (the period) or frequency (cycles per second), not a distance. Radians measure angle, an angular quantity, not a length. Miles is a distance, but it’s not the conventional unit used in physics for expressing wavelength; meters are the standard unit, with other units (like centimeters or kilometers) used only as convenient alternatives.
