If the distance from a crest to the next trough is 1 meter, the wavelength is 2 meters, because wavelength is measure from crest to crest.
Electromagnetic radiation is just light. You can measure light with a light meter, which tells you intensity, or a camera sensitive to different frequencies. You can also use a magnetometer (Gaussmeter) to measure the B field component or a voltmeter to measure the E field component.Your eyes are instrumentstha measure EM radiation between 300 and 700 microns. We call this type of EM radiation "visible light." Other detectors of EM radiation ar CCD chips in digital cameras, and IR detectors in appliances with rerote controls.spectroscope?
The SI unit is meter. But nanometer and angstrom are commonly used units to measure the wavelength of light.
Gamma rays. They have a wavelength of 10 picometers, or ten trillionths of a meter.
Energy E and wavelength w are related by a constant ,Ew= hc = .2E-24 Joule -meter.

Divide the speed by the wavelength. (For any wave, the wavelength times the frequency is equal to the speed of the wave.)
The wavelength for visible light is between 400-800nm Range. nm: Nano Meter (0.000000001 or 1/1000000000 of Meter)
The wavelength of infrared between four hundred to seven hundred mitro meter
