Answer 4

Amplitude Modulation and Frequency Modulation.  The names describe how the radio waves that carry the signals are differentiated from each other.  AM varies the length of the waves and FM varies how quickly they pulse.  This is why the stations are designated by Hertz and Megahertz.  Those units are used to measure wavelength and frequency.

Answer 5

Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave.

FM is commonly used at VHF radio frequencies for high-fidelity broadcasts of music and speech. Normal (analog) TV sound is also broadcast using FM. A narrow band form is used for voice communications in commercial and amateur radio settings.
