Q1: Electromagnetic spectrum is divided into different regions depending on their frequency and application. Explain the relationship between the frequency and wavelength of the electromagnetic waves, illustrating this with the presentation of the electromagnetic spectrum for the radio frequencies between very low frequency (VLF) and the Extra High Frequency (EHF) bands.
