It depends, if you mean light or sound waves, for example, there are a variety of factors to be measured:
The length of a wave from peak to peak is represented with lambda.
You can also measure velocity of a wave (how fast and in what direction it is moving).
Frequency of light effects the color of the light, and frequency of sound effects its pitch.
Intensity
Loudness is determined by the amplitude of the sound waves.
Usually, no. The wavelength of visible light is usually measured in nanometers. Only larger forms of electromagnetic radiation, like radio waves, are measured in meters.
its a measurement of cycles per second of sound or other waves and Hertz is the scientist who invented the scale of measurement
The loudness of a quarry depends on the type of quarry and how far away you are measuring its sound waves. If measured close up, the decibels will be higher than from further away.
They are measured on the Richter scale.
Your brain waves are measured.
Earthquake waves (seismic waves) are measured using a seismograph or seismometer.
Its frequency.
googoe
Answer is by sound waves
The frequency of electromagnetic waves is measured in hertz (Hz), where 1 Hz equals one cycle per second.
It is measured in Hertz (Hz).
measured by a ruler lol
waves are measured in Joules
