If wavelength is in meters per second what is frequency in?

Answer 1

The unit of frequency is always 'reciprocal time' ... "per second", "per minute", "per hour", etc.,

no matter what the speed or wavelength may be.

Examples:

Speed = 10 meters per second, wavelength = 2 meters.

Frequency = (speed) / (wavelength) = (10 meters / sec) / (2 meters) = 5 per second.

Speed = 100 yards per hour, wavelength = 1 mile

Frequency = (speed/wavelength) = (100 yd/hour) / (1 mile) =

(100 yd/hour-mile)x(1 mile/1760 yd) = (100/1760) per hour.

Speed = 60 ft/sec, wavelength = 1 inch

Frequency = (speed/wavelength) = (60 ft/1 inch-sec) x (12 inch/ft) = 720 per sec.

Answer 2

Frequency is measured in hertz (Hz), which represents the number of cycles or oscillations of a wave that occur in one second. It is the reciprocal of the wavelength.
