Rnav : Basic Radio Propagation

What is the velocity of an electromagnetic wave?

What is the amplitude of wave?

What are the 8 Frequency bands and Frequencies of the different wavelengths including their propagation path?

Answer explanation

kHz

VLF = 3 - 3O (ground wave)

LF = 30 - 300 (ground wave)

MF = 300 - 3000 (ground wave)

MHz

HF = 3 - 30 (sky wave)

VHF = 30 - 300 (direct wave)

UHF = 300 - 3000 (direct wave)

GHz

SHF = 3 - 30 (direct wave)

EHF = 30 - 300

What are the formulas to calculate Wavelength and Frequency?

What is the velocity  of the radiowave in Km/s , m/s and in NM/S?

What is the wavelength of an NDB transmitting on 375kHz?

What type of modulation is N0N?

What equipment uses pulse modulation?

A radio signal may be classified by 3 symbols, What indicates 1st, 2nd and 3rd symbols?

(example: A2A)

What happens to the wavelength when the frequency of an electromagnetic wave is increased?
