Radio theory to double effective range of a radio transmission power output must be increased a factor of
Question Section 5: Navigation 26 Answer 9

Radio theory 'fading' Interference between surface wave sky wave, disappearance of layer d at dusk, reflection of waves on ionosphere, an abnormal increase in amplitude of electromagnetic waves.
Question Section 5: Navigation 26 Answer 10

Radio theory radio waves travel at The speed of light, the speed of sound, a speed depending on type of electromagnetic waves, a speed just below speed of sound.
Question Section 5: Navigation 26 Answer 11

Radio theory radio waves travel at a speed of 3km/s, 3 km/s, 3m/s, 3 m/s.
Question Section 5: Navigation 26 Answer 12

Radio theory a radio signal looses strength as range from transmitter increases this called Attenuation, refraction, propagation, ducting.
Question Section 5: Navigation 26 Answer 13

Radio theory an electromagnetic wave has two types of energy field An e electrical field h magnetic field, an h electrical field an e magnetic field, a z electrical field an h magnetic field, a z magnetic field an e electrical field.
Question Section 5: Navigation 26 Answer 14

Radio theory an electromagnetic wave consists of an oscillating electric field e and an oscillating magnetic field h which statement correct The (e) (h) fields are perpendicular to each other, a dipole antenna can only transmit field (h), the (h) field parallel to wire field (e) perpendicular to wire, when ac current pass through antenna, fields (e) (h) are parallel.
Question Section 5: Navigation 26 Answer 15

Radio theory an electromagnetic wave consists of an oscillating electric field e and an oscillating magnetic field h their propagation speed The speed of light, the speed of sound field (e) the speed of light field (h), the speed of light field (e) the speed of sound field (h), the speed of sound.
