Literally have no idea what I'm doing here. Been searching for God knows how long trying to get a slight idea about this.

My question is:

The frequency of an electromagnetic wave is measure to be 4.997 x 10^5 (it also has 's^-1' after it if that makes any difference)

What type of electromagnetic wave is it?

Helllllllppppppp! Any advice would be great, thanks!

Assume that the wave travels at the speed of light and then use the equation v=f\lambda to find the wavelength. Then you should be able to see the type of electromagnetic wave from a wavelength spectrum or you may know roughly how each wavelength corresponds to each type of EM radiation

\rm f =4.997 \rm x 10^{5}\ Hz = 0.4997\ MHz = 499.7\ kHz

\lambda = \frac{v}{f} = \frac{300 \rm x10^{6}}{0.4997 \rm x 10^6} = 600.36 \rm\ Metres

600 metres wavelength is between the Low and Medium Wave radio frequency wavelengths.

495kHz to 505kHz is reserved for civil maritime mobile radio communications within the UK and EU.

UK185 Ofcom may licence stations in the Maritime
Mobile service in this band.

EU1 Commission Decisions 2006/771/EC,
2008/432/EC, 2009/381/EC, 2010/368/EU and
2011/829/EU (harmonised use of spectrum for
short range devices (SRDs)) applies.
