That depends a lot on the order of magnitude of the electromagnetic radiation in question. If it's radio waves or microwaves, you can use a coil of wire hooked up to an oscilloscope (preferably a digital one), and use a function on the device to measure the wavelength.
If it's something between infrared and ultraviolet, including visible light, you'd have to use a special light sensor, though I'm not sure of the name. However, there is a relatively simple experiment that can give you a rough estimate of the wavelength of light you can see:
As for things like X-rays and Gamma rays, sorry, but I have no clue, though I can speculate that it would be possible to take a diffraction based approach such as the one outlined on the link above, but the equipment would surely be more complicated. Not to mention that such forms of radiation are very dangerous.

It will become longer, and it will carry less energy, its also likely, that if the change or loss in frequency is enough, the radiation will become a different type of electromagnetic radiation in the spectrum like gamma to x-rays or visible light to infrared and so on.
a microwave is an electromagnetic wave.================Answer #2:A microwave is a radio wave with a wavelengthless than 10 cm (frequency greater than 3 GHz).
For any point on the electromagnetic spectrum, the product of(wavelength) multiplied by (frequency) is 299,792,458 meters per second.That's the speed of the wave.
Electromagnetic waves vary in frequency, wavelength, and energy. These properties determine the type of electromagnetic wave, such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of electromagnetic wave has unique characteristics and uses.
The wavelength of an electromagnetic wave is inversely proportional to its frequency. This means that as the frequency of the wave increases, its wavelength decreases, and vice versa.
Radio waves have the longest wavelength in the electromagnetic spectrum.
Some examples of wavelength questions that can be used to study the properties of electromagnetic radiation include: How does the wavelength of light affect its color? What is the relationship between wavelength and energy in the electromagnetic spectrum? How does the wavelength of a radio wave affect its ability to transmit information? How does the wavelength of ultraviolet radiation impact its effects on living organisms? How does the wavelength of infrared radiation influence its ability to detect heat signatures?
Wavelength = 1/Frequency

As the wavelength of an electromagnetic wave decreases, the frequency of the wave increases. This means that the energy carried by the wave also increases, as energy is directly proportional to frequency. Therefore, shorter wavelength corresponds to higher frequency and energy in an electromagnetic wave.
frequency
If you know the wavelength of an electromagnetic wave in a vacuum, you can calculate its frequency using the equation speed = frequency x wavelength, where the speed is the speed of light in a vacuum (approximately 3 x 10^8 m/s). The frequency of an electromagnetic wave is inversely proportional to its wavelength, so as the wavelength decreases, the frequency increases.
The longer an electromagnetic wave's wavelength, the lower its frequency. This means there are fewer wave crests passing a point in a given time, resulting in a longer distance between crests.
radio wave is form of electromagnetic energy which has the longest wavelength in electromagnetic spectrum
A gamma ray is an electromagnetic wave. It has the highest frequency (and energy) as well as the shortest wavelength on any wave on the electromagnetic spectrum.
The frequency and wavelength of an electromagnetic wave are inversely related: as frequency increases, wavelength decreases, and vice versa. This is because the speed of light is constant, so a higher frequency wave must have shorter wavelengths to maintain that speed.
