Yes. The instrument is referred to as a "frequency counter".
It's a common piece of telecommunications test equipment.
Frequency is measured in Hertz, not metres per second.
Frequency = speed/wavelength = 300,000,000/150 = 2 MHz
Since there are several kinds of waves, there are several ways to measure their frequency. Electrical waves can be measured with a frequency counter, an analog frequency meter or an oscilloscope. Ocean waves' frequency is measured with a stopwatch, but most people who measure ocean waves want to know how large they are rather than how fast they're coming.
A watt meter measures the electric power in watts from circuits. They can measure utility frequency, audio frequency power and radio frequency measurement.
Purely arbitrary, but the most common division is by wave-length. i.e. 1 meter, 2 meter, etc
frequency meter is used to measure the frequency of unknown frequency signal.
Just like any other wave phenomenon, its frequency is measured in large multiples of Hertz (Hz), its wavelength is measured in small fractions of a meter (m), and its speed is measured in meters/second .
Frequency = speed/wavelength = 300,000,000/2 = 150,000,000 = 150 MHz. (The ham-radio band from 144 to 148 MHz is usually called the "two-meter band".)
The frequency of a wave is measured in Hertz.
Wavelength is a length. Hence, the metric unit for it is "meter". Frequency is a reciprocal of time. Hence, the unit for it is "per second", named "Hertz".
The frequency of a radio wave in Hertz (cycles per second) multiplied by the wavelength of the radio signal (in meters) is always equal to the speed of light, which is equal to The speed of light has the symbol "c". So Frequency/c = wavelength, and wavelength/c = frequency. == ==
The frequency, or number of cycles per second is measured, then divide the speed of light in meters per second (299,792,458) by frequency to get wavelength in meters. Example: 7 Mhz = 7,000,000 hz 299792458 / 7000000 = 42.8 meters.
