How do you work out the wavelength of an electromagnetic wave without being given the frequency? Or how do you work out frequency or wavelength off an unlabelled basic wave diagram?

Count the number of waves in the diagram and assume it as the frequency?

What's your context? If you have a diagram showing said wave, then you'll need to use a ruler to measure the distance between two identical points on a wave (e.g. peak to peak). Alternatively, is the type of electromagnetic wave stated (radio, infrared etc.)? If so, you can find the wavelengths/ frequencies online.
